During the TROUGHS (Tropical Ridge Observations of Underwater Geochemical Hydrothermal Signals) expedition we collected hydrothermal plume particles along a 350 km section, extending from approximately 8 degrees 40'N to 11 degrees 50'N, of the EPR north and south of the Clipperton Transform Fault. Over the segment south of the Clipperton Transform Fault, the S/Fe ratio in the particles ranged from about 0.9 to 10, with the highest values immediately over the new vent field at the 9 degrees 45.52'N site. These enrichments exactly coincide with the elevated (super 3) He/heat and CH (sub 4) /Mn ratios in the plumes over the same vent field. The S-rich particles are primarily organic and may be related to the 'bacteria blizzard' associated with the eruption. In addition, very high Cu/Fe and Zn/Fe ratios were observed in the hydrothermal plumes south of the Clipperton Transform Fault. These high ratios are indicative of the predominance of high-temperature, H (sub 2) S-rich vents between 9 degrees 35'N and 9 degrees 50'N. In contrast, the samples from the segment north of Clipperton Transform Fault had S/Fe ratios which ranged from 0.04 to 0.82, typical of mature, Fe-rich hydrothermal plumes. These results suggest that the gas-rich vent fluids at the 9 degrees 45.52'N site produced the sulfur-enriched particles in the water column. Gas-rich plumes and sulfur-enriched plume particles were also observed underneath the 1986 Megaplume on the Juan de Fuca Ridge (JdFR), suggesting a similar mode of formation. North of the Clipperton Transform Fault, the hydrothermal particles are dominated by Fe-rich oxyhydroxide particles, characteristic of mature high-temperature vent fields. The plume maximum is centered at 11 degrees 08'N. The Fe oxyhydroxide particles scavenge Ca, Si, P, V, Cr and As from seawater. For P and V the mean element/Fe ratios in the EPR hydrothermal particles are intermediate between JdFR and TAG hydrothermal systems. For As the mean element/Fe ratios of all three systems are about the same. New evidence for Si scavenging by hydrothermal Fe oxyhydroxide particles indicates that this sink for dissolved Si in the oceans is small.

We find that steep subduction was well developed by 2.5 Ga, which coincides with a major change in sedimentary rare-earth element patterns. Over 50% of all oceanic crust subducted steeply by 2.0-1.6 Ga, the same interval over which the average thickness of continental plates declined rapidly. Because producing thick plates requires many episodes of flat subduction, our model can explain why there are no known thick plates <1.6 Ga.

Pinatubo eruption AN - 50185991; 1995-015034 AB - NOAA has been archiving weekly and monthly gridded analyses of "radiatively equivalent" aerosol optical thickness over oceans on magnetic tape since June 29, 1989. These analyses are derived from the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA-11 polar orbiting environmental satellite. The eruption of Mt. Pinatubo in June 1991 and the ensuing dispersal of aerosol particles in the stratosphere occurred after two complete years of observations with essentially "background" particle concentrations in the stratosphere. This fortunate timing means that computing the difference between the average of the first two years of tropospheric aerosols and the "Post-Pinatubo" period of tropospheric and stratospheric aerosols provides a means of observing the evolution of the stratospheric aerosol cloud. Time series of zonal averages of these difference fields are presented and analyzed. These analyses indicate that by the end of 1993, the stratospheric aerosol optical thickness declined from its peak value in late Summer of 1991 to levels that are no longer detectable with AVHRR data.

The chemical properties of these two lenslike masses of water were described by Baker et al. (1989) and clearly indicate that they were generated by massive and rapid ventings of hot hydrothermal fluid from the ridge. Both are nearly circular with radii of about 6.5 km. The isopycnals bow upward around these cores of anomalous water, leading to an anticyclonic circulation. A cyclogeostrophic balance gives maximum currents at the edge of the core of 0.11 m s (super -1) for the first megaplume (MP1) and 0.07 m s (super -1) for the second megaphone (MP2). Currents extend beyond the core to a radius of 12-15 km. The centers of the cores are in nearly solid body rotation with relative voracities of -0.5f(MP1) and -0.3f(MP2) and potential vorticity anomalies, expressed in units of equivalent relative vorticity, of -0.8f(MP1) and -0.6f(MP2), where f is the Coriolis frequency. The aspect ratio of each megaplume gives a Burger number of 0.22. In terms of these nondimensional numbers, the megaplumes are very similar to eddies of Mediterranean water found in the eastern Atlantic (meddies), despite their very different origin.

Results are presented from a study on the sex ratio of spawning populations that also examined the duration of the spawning season and the biological parameters of sexual maturity. Sampling data were collected over the period 198692. While females were predominant, immature males exceeded immature females by two to one. Gonosomatic indices and ovarian histological data indicated a potential 89-week spawning season beginning in mid-August and extending into October. Greater than 50% maturity was achieved by both sexes by age 4 yr. Sexual maturity was unrelated to size, but males were found to mature at slightly lesser length and weight than females. A 7-yr averaged spawning frequency of 8.8 d was determined, with a mean batch fecundity of 1.54 million ova.

Female cobia with ripe ovaries have been collected in the northern Gulf of Mexico from April through October. Spawning takes place throughout the summer. In order to assess changes in biochemical composition of the cobia ovary throughout the course of gonadal development, total protein, lipid, carbohydrate, and ash were measured for fish sampled on their Gulf of Mexico spawning grounds. Data are presented on cobia histology, timing of ovarian development, the gonosomatic index, and biochemistry. The analysis reveals that protein is the major constituent of cobia ovaries, which remains fairly constant throughout all stages of gonadal development. Lipid was the second most abundant component, and fluctuations could be explained by the increasing amount of lipid yolk reserves deposited as oocytes mature. Carbohydrate was the least abundant component.

A surplus production model (SPM) is developed to manage the reef fisheries of Jamaica and Belize. The fisheries of Belize have been lightly to moderately exploited, while those of Jamaica have been overexploited. Surveys were conducted of catch and effort to better quantify the model in relation to underlying assumptions. The catch and effort data were summed by area, gear type, and species group, and were standardized per km super(2) of each fishing ground. Yield from Jamaican and Belize waters was found to be 552 and 340 kg/km super(2), respectively. However, the mean fishing effort was found to be 15 times higher in Jamaica than in Belize, while the catch rate was nine times higher in Belize than in Jamaica. The composition of the fisheries was also substantially different in the two countries. Results of the SPM suggest that the Belize fishery is capable of further expansion in most areas.

In an effort to assess the extent of the problem, the foraging characteristics of sea otters were determined in relation to the length of habitat occupancy. The data evaluated, which were gathered by observation, included sex and age class, presence of pups, number of prey items obtained during foraging, and identification and categorization of prey. Statistical methods were used to assess differences in the proportion of shellfish captured among study areas and differences in forage success among study areas and adult sex classes. The percentage of clams, mussels, crabs, and green sea urchins foraged was found to be 5767, 1925, 24, and 03%, respectively. Forage success did not differ among study sites nor among sex classes. Mean forage success for all study areas combined was 89% for adults and 90% for juveniles.

Based on a 199091 sampling of commercial poundnet, haul-seine, and gillnet catches in the Chesapeake Bay and adjacent waters, annual fecundity was determined, along with spawning periodicity, size and age at maturity, sex ratios, ovarian cycle, and oocyte atresia. The sampling and analysis methods are described. Results indicated that males and females start to mature at 170 and 150 mm, respectively, and that more than 85% of both sexes are mature by the end of their first year. The spawning period was found to be JulyDecember, although individuals were found to spawn over a shorter period. Wide temporal fluctuations were found in terms of sex ratios: the frequency of males decreased in June and July, reaching a minimum in SeptemberOctober. Oocyte development appeared to be asynchronous. Spawning females exhibited a high incidence of atresia of advanced yoked oocytes throughout the spawning season.

AN - 15222190; 4830 AB - PURPOSE: The amending of the fishery management plan (FMP) for coral reefs in state and federal waters off the Florida coast is proposed. The amendment would establish special protections for live rock, a rock substrate composed mostly of calcium carbonate that supports diverse invertebrate life forms. Live rock is harvested by divers who selectively remove small pieces from the bottom either by picking up loose rubble rock or chipping rock from reefs or ledges; the rock is ultimately sold to collectors, dealers, and hobbyists for use in marine aquaria. It is estimated that in 1991, some 600,000 pounds of live rock were removed from waters adjacent to Florida. The South Atlantic Fishery Management Council has determined that removal of the live rock constitutes the removal of a fishery habitat. Under the preferred alternative, the amendment would establish an annual quota of 485,000 pounds of loose rubble rock in the South Atlantic, south of Broward-Dade County, Florida line for 1994 and 1995. Harvesting in these waters would terminate no later than January 1, 1996. No take, possession, or chipping of live rock in waters north of Dade County would be permitted. In the Gulf of Mexico harvesting would be allowed to continue through 1996 from the Florida-Alabama state line to the Monroe-Collier county line in Florida; no chipping would be allowed north and west of the Pasco-Hernando county line to the Florida-Alabama border. During the phase-out harvest period, a federal permit would be required for the harvest and possession of live rock. Permits would be limited to persons who have commercially landed and reported live rock landings prior to February 3, 1994. Some exceptions would be allowed for aquacultural harvests. Permitted vessels would be limited to 25 five-gallon buckets of live rock per daily trip. POSITIVE IMPACTS: The amendment to the FMP would protect the coral reef and hard-bottom habitats around Florida; in some areas the removal of live rock by harvesters has severely damaged the limited outcroppings or rock ledges in state and federal waters. The effects of harvest restrictions on the aquarium industry would be minimized as material from aquacultural operations replaces live rock. NEGATIVE IMPACTS: Habitat degradation would continue during the phase-out of live-rock harvesting. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

AN - 76720726; 8092995 AB - The thermodynamics of binding of fluoride and cyanide to cytochrome c peroxidase (CCP) and its Asn-82-->Asp mutant (D82CCP) in phosphate and acetate buffer at an ionic strength of 0.15 mol.kg-1 from pH 5.0 to 7.1 were investigated by titration calorimetry at 289 and 297 K. The binding reactions are enthalpically driven. The fluoride-binding constants determined from the titration calorimetry results were in agreement with those determined from difference-spectroscopy measurements. For cyanide binding to CCP at 297.9 K, the binding constant decreased from 8.95 (+/- 0.83) x 10(5) M-1 at pH 7.0 to 4.04(+/- 0.23) x 10(5) M-1 at pH 5.0, and the binding enthalpy increased from -57.2 +/- 1.4 kJ.mol-1 at pH 7.0 to -48.6 +/- 1.8 kJ.mol-1 at pH 5.0. For fluoride binding to CCP, the binding constant increased from 8.41(+/- 0.54) x 10(3) M-1 at pH 7.0 to 3.11(+/- 0.09) x 10(5) M-1 at pH 5.0 and the binding enthalpy increased from -71.9 +/- 1.1 kJ.mol-1 at pH 7.0 to -67.0 +/- 1.9 kJ.mol-1 at pH 5.0. The binding enthalpies for D82CCP were about the same as those for CCP. However, the binding constants for cyanide and fluoride to D82CCP were respectively a factor of two less and at least an order of magnitude less than the corresponding binding constants of CCP. Decreased ligand-binding strength in the D82CCP mutant is thus entirely due to entropic effects.

AN - 62743805; ED378511 AB - This report presents findings on children's living arrangements as taken from the Survey of Income and Program Participation (SIPP). The SIPP is unique in that it records how each person is related to everyone else in the household. Detailed information on parent-child relationships is provided, allowing identification of biological, step, foster, and adoptive ties. Similar data are collected for siblings. With this additional information, it is possible to examine family structure in more detail than was possible in previous Bureau of the Census reports. The statistics contained herein are based on national-level estimates of children under 18 and their living situations, for the period June through September, 1991. The report's findings pertain to all children, regardless of their marital or parental status. Included in these findings was the fact that 73 percent of children under age 18 lived with two parents, 24 percent lived with one parent, and 3 percent lived with neither parent. Black children were 2.5 times more likely to live in a one-parent family than were White children. The report examines both traditional nuclear families and nontraditional families, and includes data on children in blended families, adopted children, extended families, and other arrangements. Five figures and 12 tables summarize the data. Appendixes include an overview of the SIPP program, definitions and explanations of terms, and source and accuracy of estimates.

Using data from the Wave 5 component of the 1990 Survey of Income and Program Participation (SIPP), the report examines patterns of school enrollment, education costs, financial aid, and the associated characteristics of postsecondary students in the U.S. The report includes those enrolled in two-year and four-year colleges as well as vocational, technical, and business schools. The tabulations show the numbers of high school graduates enrolled in postsecondary institutions by a variety of demographic, social, and economic characteristics. Other tabulations show the average costs, financial aid received, net costs, and numbers of aid recipients by level of enrollment. These tabulations are crossed by gender, family income, race/ethnicity, and student dependency status. Appendices provide tabulations referring to the school year 1987-1988, an overview of the SIPP program, definitions and explanations, an analysis of the source and accuracy of the estimates and the data quality, and a copy of the questionnaire. The report's highlights indicate that the average total cost of schooling was $2,653 per student, and that among those students who received some kind of financial aid, about 75 percent of their costs were covered.

Although much of the primary literature indicates that amorphous matter is a major component of the stomach contents of Atlantic menhaden, the diet of these fish is typically perceived to consist primarily of phytoplankton and zooplankton. This disparity between observation and perception results from the belief that amorphous matter in the stomachs is the remnants of plankton that were ingested alive or that it is detritus of low nutritional value and only incidentally ingested. In this study, we found that the stomach contents of juvenile and adult Atlantic menhaden in estuarine creeks were 81% amorphous matter, 17% phytoplankton, and 1% zooplankton, by dry weight. Sampling in two estuarine creeks in North Carolina revealed no seasonal change in diet. Stomachs of fish collected from coastal waters contained smaller amounts of amorphous matter (47%) and higher amounts of phytoplankton (36%) and zooplankton (18%) than stomachs of fish from estuarine creeks. The higher concentration of plankton in the diet of fish in coastal locations probably reflects the lower concentration of suspended amorphous matter and higher relative abundance of plankton typical of that environment. In stomachs that contained largely amorphous matter, the concentrations of ash (70%, dry weight) and humic compounds (38%, ash-free dry weight [AFDW]) were high and the carbohydrate content was moderately low (14%, AFDW). On the basis of reported concentrations of these compounds in plankton and amorphous aggregates, we conclude that the amorphous matter we found in the stomachs of Atlantic menhaden was not recently ingested living or moribund plankton, but was probably material that was produced in the environment by the aggregation of dissolved organics from various detrital sources, including decaying vascular plants. If vascular plants contribute to the production of amorphous matter, their role in coastal and estuarine energy flow and fishery production may be underestimated.

Statistical Brief. AN - 62639428; ED388706 AB - Data from the Census Bureau's Current Population Surveys show that it is definitely worth, in economic terms, staying in school and earning a higher degree. This Brief examines the relationship between education and earning during the 1992 calendar year and demonstrates how the relationship has changed over the past 2 years. It also provides estimates of the total earnings adults are likely to accumulate over the course of their working lives. The more education adults received, the more money they made. Lifetime earnings estimates for seven educational levels demonstrate the large earnings differences that develop between educational levels over the long term. While high school dropouts could be expected to earn about $600,000 in 1992 dollars over a lifetime, completing high school could add about $200,000, and completing a bachelor's degree could add nearly another half million dollars. Such differences may become even more striking in the future, particularly if current trends in the consumer price index continue. Two graphs illustrate mean annual and lifetime earnings.

Analysis of the C (sub 6) + fraction constituents of natural gas is technically complex and expensive. The assembly of a physical properties database for known C (sub 6) + fraction constituents is needed to facilitate the development of improved chromatographic separation procedures for analyzing raw and processed natural gas streams for compliance with gas quality and end use specifications. This report provides a critically reviewed compilation of physical properties data for 132 hydrocarbon compounds identified as being native constituents of natural gas, 21 gas treatment compounds, and 23 gas odorant compounds. The physical properties data include: molecular mass, normal boiling point, critical temperature, critical pressure, critical density, acentric factor, triple point temperature, melting point, molar volume at normal boiling point, and refractive index. The database was compiled using information obtained from a comprehensive search of the public domain technical and patent literature using all major on-line chemical literature, patent abstract, and database services.

AN - 76629031; 8044628 AB - A rapid method has been developed to screen for planar chlorobiphenyl (CB) congeners, as well as certain other CBs and DDTs, in tissue samples from marine biota. The analytes were extracted from tissue matrices with 1:1 hexane/pentane (v/v) and interfering compounds were separated from the CBs on a gravity-flow column packed with acidic, basic and neutral silica gel eluted with 1:1 hexane/methylene chloride (v/v). Subsequently, the planar CB congeners were resolved from the DDTs and other CBs by HPLC on Cosmosil PYE analytical columns cooled to 9 degrees C and were measured by an ultraviolet (UV) photodiode array (PDA) detector. Two important advantages of PDA over conventional UV detection were the ability to identify individual analytes by comparing their UV spectra to those of reference standards and the ability to establish the spectral homogeneity (purity) of the analytes by comparing spectra within a peak to the apex spectrum. The HPLC/PDA method was tested with tissue samples from fish, shellfish and marine mammals; concentrations of certain CBs and DDTs in samples determined by screening compared favorably with those in the same samples analyzed by a comprehensive method (e.g., gas chromatography/high resolution mass spectrometry). However, the HPLC/PDA method was about an order of magnitude less sensitive than determinations by comprehensive methods.

We have selected those rocks whose compositions indicate that they are either normal mid-ocean ridge basalts (MORBs) or hotspot-type MORBs. Then we used the data base to calculate the most primitive liquidus temperature for each rock suite. The results show that the liquidus temperature of the Phanerozoic ophiolites ranges from a low of 1212 degrees C to a high of 1417 degrees C. Using these data and two exponential curves bracketing the maximum and minimum temperatures versus time, we infer that the Phanerozoic suites had a mean liquidus temperature of 1272+ or -7 degrees C and a mean temperature range of 1218 degrees to 1425 degrees C. The liquidus temperatures of Archean MORBlike greenstones range from 1305 degrees to 1576 degrees C. Using these data and two exponential curves bracketing the maximum and minimum temperatures versus time, we infer that Archean melts at 2.8 Ga had a mean liquidus temperature of 1399+ or -13 degrees C and a temperature range from 1301 degrees to 1533 degrees C. Using two different methods, we show that the change in the mean liquidus temperature since the late Archean is from 96+ or -13 degrees C (from temperature ranges) to 127+ or -20 degrees C (from temperature means). When we convert these liquidus temperatures to potential temperature of the mantle, we find that the change in the mean upper mantle potential temperature since the late Archean is from 137+ or -8 degrees C (from temperature ranges) to 187+ or -42 degrees C (from temperature means). This change is less than that which was previously thought to have occurred. We compared the liquidus temperatures calculated from our data set with an independent data set from the modern day Pacific plate. The resulting histograms have the same shape and the same temperature range, showing that our method for calculating mantle temperatures from MORBlike rocks in ophiolite suites is valid. When our calculated liquidus temperatures for all time intervals are plotted in histograms, the resulting distributions are not bimodal, but skewed unimodal. That is, the distributions show a high-T tail which results from the presence of hotspot magmas in the data set. The Archean temperature distribution is also skewed unimodal, and the high-temperature Archean rocks, such as komatiites, plot in the hotspot area of the distribution. This strongly supports the contention that komatiites do not represent "normal" Archean mantle but rather were probably erupted by hotspots. Our data suggest that the relative proportion of hotspot magmas in oceanic lithosphere has remained nearly constant over geologic time.

AN - 36406924; 4565 AB - PURPOSE: The issuance of a deep seabed mining exploration license to Ocean Minerals Company (OMCO) is proposed. The license would be in effect for ten years and apply to the Pacific Ocean equatorial high seas, roughly between Central America and Hawaii, an area known as USA-4 that was previously licensed to the Kennecott Consortium. The applicant would use existing mineral deposit data to resolve the remaining unknown factors affecting permit area delineation, perform environmental analysis of the existing data, and conduct ongoing re-evaluations of commercial development. OMCO has already compiled significant data from the USA-4 area related to mineral deposit characterization, mining system performance, and benthic biological composition. The primary efforts to be undertaken under the license would consist of specifying future development methods and schedules based on these existing data, augmented with information gathered from extensive developments in technology. The license does allow an applicant to take from the deep seabed such quantities of any hard mineral resource as is necessary for the design, fabrication, and testing of equipment to be used in the commercial recovery and processing of that mineral. However, no at-sea equipment tests would be undertaken by OMCO until a supplemental site-specific EIS were issued. No other recovery activities would be allowed under the license. POSITIVE IMPACTS: The licensed activities would provide the necessary resource, technological, and economic information for OMCO to be in a position to apply for a commercial recovery permit, should the economy warrant it. NEGATIVE IMPACTS: The worst case potential for environmental impact during exploration activities would occur from seafloor sampling with basket samplers, likely to recover up to a ton of nodules from the ocean floor. These nodules would be used for onshore testing of the collector system or in further onshore processing development tests. However, this activity would not have any significant adverse effect.

AN - 62708232; ED375310 AB - Data collected by the March Current Population Survey were used to identify which groups of year-round, full-time civilian workers aged 16 and older were most likely to be at the top and bottom of the earnings ladder. Women, young workers, less-educated individuals, and Hispanics were most likely to earn less than $13,091 (1992 constant dollars), whereas men, college degree holders, and whites were most likely to earn at least $52,364. Although more females than males have low earnings, the likelihood of having low earnings has risen faster among men than women. Consequently, the percentage point gap between males' and females' respective earning rates closed from 13 points in 1979 to 9 points in 1992. The number of low-paid workers between the ages of 18 and 24 increased 19 percentage points between 1979 and 1992. Thirty-one percent of men without a high school diploma were low earners as opposed to only 5% of those with a bachelor's degree. Thirty-five percent of men and 10% of women with at least a bachelor's degree were high earners. White women enjoyed the biggest income gains between 1979 and 1992.

Recently, a global optimization method known as the SCE-UA (shuffled complex evolution method developed at the University of Arizona) has shown promise as an effective and efficient optimization technique for calibrating watershed models. Experience with the method has indicated that the effectiveness and efficiency of the algorithm are influenced by the choice of the algorithmic parameters. This paper first reviews the essential concepts of the SCE-UA method and then presents the results of several experimental studies in which the National Weather Service river forecast system-soil moisture accounting (NWSRFS-SMA) model, used by the National Weather Service for river and flood forecasting, was calibrated using different algorithmic parameter setups. On the basis of these results, the recommended values for the algorithmic parameters are given. These values should also help to provide guidelines for other users of the SCE-UA method.

The purpose is to reduce eolian transport of dust from the Gobi Desert. Preliminary data indicate a negative trend in dust-storm frequency and duration since the 1960s. Effects on atmospheric radiation and cloud microphysics appear to be statistically insignificant in the studied period. However, only time can show any long-term impact on our environment.

We analyzed long-period surface waves and P waves recorded on the IRIS stations to estimate the fault parameters. The Centroid Moment Tensor solution shows that the focal mechanism is a thrust type with the strike parallel to the Aleutian trench. The seismic moment is 2.0X10 (super 19) Nm and the corresponding moment magnitude is 6.8. The Moment Tensor Rate Function inversion from P waves also yields a similar focal mechanism and seismic moment. In addition, this computation provides estimates of 10 s for the duration of the source time function and 35 km for the best point source depth. These seismological analyses indicate that the fault mechanism of the 1993 earthquake was as expected, but that the magnitude was too small to fill the gap. This earthquake did not generate a tsunami large enough to be observed at the Sand Point, Alaska tide gauge or at an ocean bottom pressure gauge, at distances of 100 and 300 km, respectively. Numerical tsunami simulations result in amplitudes at both stations that are within the background noise level. Additional numerical experiments also suggest that the small tsunami amplitudes are due to the location of the source area in the shallow shelf region.

AN - 36393006; 4627 AB - PURPOSE: The amending of the fishery management plan (FMP) for coral reefs in state and federal waters off the Florida coast is proposed. Under the amendment, special protections would be established for live rock, a rock substrate composed mostly of calcium carbonate that supports diverse invertebrate life forms. Live rock is harvested by divers who selectively remove small pieces from the bottom either by picking up loose rubble rock or chipping rock from reef for ledges; the rock is ultimately sold to collectors, dealers, and hobbyists for use in marine aquaria. It is estimated that in 1991, some 600,000 pounds of live rock were removed from waters adjacent to Florida. The South Atlantic Fishery Management Council has determined that removal of the live rock constitutes the removal of a fishery habitat. Under the preferred alternative, an annual quota of 485,000 pounds of loose rubble rock in the South Atlantic, south of Broward-Dade county line in Florida would be established for the 1994-1995 period. Harvesting in these waters would terminate no later than January 1, 1996. No take, possession, or chipping of live rock in waters north of Dade County would be permitted. In the Gulf of Mexico a quota of 252,000 pounds of harvesting for the 1994-1996 period would be established from the Pasco-Hernando county line to the Monroe-Collier county line in Florida; however, no chipping would be permitted in these waters and no harvesting or possession of live rock would be permitted outside this designated area. During the phase-out harvesting period, a federal permit would be required for the harvesting and possession of live rock. Permits would be limited to persons who have commercially landed and reported live rock landings prior to February 3, 1994. Some exceptions would be allowed for aquacultural harvesting. Permitted vessels would be limited to 25 five-gallon buckets of live rock per daily trip. POSITIVE IMPACTS: Under the amendment to the FMP, the coral reef and hard-bottom habitats around Florida would be protected; in some areas the removal of live rock by harvesters has severely damaged the limited outcroppings or rock ledges in state and federal waters. The effects of harvesting restrictions on the aquarium industry would be minimized as material from aquacultural operations replaced live rock. NEGATIVE IMPACTS: Habitat degradation would continue during the phase-out of live rock harvesting.

Summary data on educational attainment by age, sex, race, and Hispanic origin are shown for both years in Table 1. Other detailed data are shown for 1993 in tables 2 through 16. These tables allow the continuation of the biennial series of data from previous reports. Tables 17, 18, and 19 contain time series of data from 1940 to 1993. The detailed tables present data on educational attainment for persons aged 15 and older by age, sex, race, Hispanic origin, marital status, labor force status, occupation, income, earnings, and region of residence. Summary data are also presented for states and large metropolitan areas. Data indicate that four-fifths of adults have completed high school, and that over one-fifth have completed college. Educational levels of the population as a whole continue to rise, but there are variations by race and ethnicity. Five text tables, four figures, and 19 detailed tables present census figures.

The Scotia Sea is an outstanding example of back-arc spreading, which is revealed in some detail by free-air gravity anomaly maps derived from the latest release of data acquired south of 30 degrees S [2]. Sea surface height data for this region have been reduced to a grid of free-air gravity anomalies, and are illustrated here by means of colour shaded relief and contour maps. The new data confirm the existence of a number of inactive spreading ridges within the Scotia Sea and surrounding small basins. The amplitudes and wavelengths of gravity anomalies over these ridges conform, in general, to the expected relationship with spreading rate, except in the central Scotia Sea, where a proposed Miocene slow-spreading ridge appears to have left no clear signature. The spreading ridge axis in the east Scotia Sea comprises seven or more segments, separated by small, mainly sinistral, offsets and exhibits a median valley with depths of 200-1000 m that is reflected in free-air lows of 10-40 mGal. Near both its northern and southern termini, the gravity signature of the ridge becomes less distinct, with a less pronounced axial low. The northernmost segments of the ridge are displaced in a right-lateral sense by a feature which appears to represent a southward migrating non-transform offset. Whereas the process of spreading in Drake Passage and the east Scotia Sea was comparable to mid-ocean ridges, that in the central Scotia Sea may have been disorganized, as observed in some western Pacific back-arc basins.

This allows a more general understanding of geochemical processes in submarine hydrothermal systems, especially where a connection with sediment is not otherwise obvious (e.g., Endeavour Segment, Juan de Fuca Ridge). Based on B and delta (super 11) B corrected for wallrock reactions, all published boron and chloride data from mid-ocean ridge systems (MOR) (e.g., 11 degrees N, 13 degrees N and 21 degrees N of the East Pacific Rise), except for the Endeavour Segment, Juan de Fuca Ridge, are consistent with experimental phase separation data, suggesting a dominant control by the latter process. Fluids from sedimented ridge (SR) (e.g., Escanaba Trough and Guaymas Basin), and from back-arc basins (BAB) (e.g., Mariana Trough, Lau Basin and Okinawa Trough), when compared with mid-ocean ridge data, show expected effects of organic matter and/or sediment contributions. This is particularly noticeable from enhanced levels of Br, I, NH (sub 4) , and trace alkali metal contents (such as Li, Rb and Cs). High B concentrations and elevated delta (super 11) B in Endeavour Segment can be explained by a small, but distinguishable contribution from sediments, which is confirmed by slightly enhanced levels of Br, I and NH (sub 4) .

There are of the order of 100 individual smoker vents on approximately 10 large sulfide structures, which are localized along faults and fault intersections across the vent field. Each sulfide structure has a characteristic fluid composition, which varies very little from one vent orifice to the next, or from year to year, on a given structure. However, there are large gradients in fluid composition across the vent field, with endmember chlorinity increasing from approximately 255 mmol/kg in the SW to 505 mmol/kg in the NE. End-member concentrations of major elements are well correlated with chlorinity, and endmember volatile concentrations in the lowest chlorinity fluids are approximately twice as high as in the highest chlorinity fluids. The gradients in composition across the vent field and measured vent fluid temperatures >400 degrees C are consistent with supercritical phase separation and loss of brine phase below the seafloor. The factor-of-2 variation in CO (sub 2) (and H (sub 2) S) is larger than expected for loss of a very high-chlorinity brine. Concentrations of iron and manganese are not positively correlated with chlorinity, suggesting that temperature and pH are more important in controlling metal solubility. Elevated ammonia and bromide/chloride ratios indicate that there has been subseafloor interaction between the hydrothermal fluids and organic matter, and high boron concentrations point to a sedimentary source.

AN - 36404145; 4545 AB - PURPOSE: The amending of the fishery management plan for the Atlantic bluefin tuna is proposed. The proposed amendment would conform with recommendations of the International Commission for the Conservation of Atlantic Tunas (ICCAT), which proposed as a goal that spawning biomass should increase by 50 percent by the year 2008. This recommendation was in response to findings that the western Atlantic bluefin tuna stock was 6 to 12 percent of the levels for sustaining maximum sustainable yield. Quotas were imposed on the fishery in 1982 and they remained in effect until 1992 when a 10 percent decrease was implemented; a further stock-wide quota decrease of 15 percent was implemented in 1994. Five national quota alternatives are considered in this draft EIS, in combination with four domestic quota allocation alternatives and three access control alternatives. Under Quota A, a limit of 1,995 million tons (mt) would be imposed in 1994. It would return to the 1993 level of 2,394 mt thereafter. Under Quota B (a No Action Alternative), the current level of 1,995 mt would be retained indefinitely. Under Quota C (the ICCAT recommendation), a limit of 1,995 mt wold be retained in 1994. It would then shift to 1,200 mt thereafter. Under Quota D, the limit would shift from 1,995 mt in 1994 to 1,200 mt in 1995, and then to 800 mt thereafter. Under Quota E, all bluefin tuna fisheries would be eliminated after 1994. The domestic quota allocation alternatives include a No Action Alterative; an alternative that would permit only general and angling (fish under 70 inches) categories of fishing; an alternative that would eliminate the Gulf of Mexico incidental longline fishery; and an alternative that would close the recreational fishery. The access control alternatives would address the overcapitalization of the fishery by allocating access rights by lottery, by a limited entry scheme with a fleet-wide quota, and by individual transferable quotas. POSITIVE IMPACTS: The implementation of the ICCAT recommendations, or the imposition of similar restrictions, would help in the control of fishing mortality so as to ensure its long-term sustainability and would promote stock recovery. NEGATIVE IMPACTS: The imposition of more restrictive quotas would reduce the commercial capacity of the fishery, causing economic hardship for some users. Under the proposed amendment, the way in which the fishery is managed would be substantially changed. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

AN - 36403459; 4496 AB - PURPOSE: The drawdown of the Lower Granite Reservoir located along the Snake River near Almota, Washington, is proposed in order to obtain data on the biological response of anadromous fish to such a drawdown. The purpose of the drawdown is to determine whether increased mean water velocity through the reservoir resulting from a drawdown would increase juvenile salmonid survival and decrease travel time. In addition, data would be collected on the effects of drawdown on upstream passage of adult salmon, resident fish, wildlife, bottom-dwelling organisms, and water quality. These data will supplement data collected under baseline conditions and during a 1992 drawdown test. Four alternatives, including a No Action Alternative, are considered in this draft EIS; the action alternatives are differentiated on the basis of the juvenile collection and bypass method to be used at the powerhouse. Under the preferred alternative (Option 3A), a drawdown test would be implemented at the reservoir during the spring migration period (April 10 to June 20) of 1996. The dam would be operated to maximize flows through the powerhouse; a new gatewell tank system would be used to bypass fish entering the powerhouse. No water would be voluntarily spilled for fish. Any untagged juvenile fish would be transported or bypassed back to the river in accordance with current policy. POSITIVE IMPACTS: Under the preferred alternative, the project would maintain adult passage, control dissolved gas, and provide for collection of tagged salmonids at Lower Granite. NEGATIVE IMPACTS: Increased spill discharge would cause higher than normal levels of dissolved gas, silt, and water temperature. Sediment levels downstream from the dam would increase as would erosion along the riverbank.

Since these emissions are driven by the surface seawater concentration of DMS, it is important to understand the processes controlling the cycling of sulfur in surface seawater. During the third Pacific Sulfur/Stratus Investigation (PSI-3, April 1991) we measured the major sulfur reservoirs (total organic sulfur, total low molecular weight organic sulfur, ester sulfate, protein sulfur, dimethylsulfoniopropionate (DMSP), DMS, dimethylsulfoxide) and quantified many of the processes that cycle sulfur through the upper water column (sulfate assimilation, DMSP consumption, DMS production and consumption, air-sea exchange of DMS, loss of organic sulfur by particulate sinking). Under conditions of low plankton biomass (8 mu M nitrate), 250 km off the Washington State coast, DMSP and DMS were 22% and 0.9%, respectively, of the total particulate organic sulfur pool. DMS production from the enzymatic cleavage of DMSP accounted for 29% of the total sulfate assimilation. However, only 0.3% of sulfate-S assimilated was released to the atmosphere. From these data it is evident that air-sea exchange is currently only a minor sink in the seawater sulfur cycle and thus there is the potential for much higher DMS emissions under different climatic conditions.

Sea surface temperature (SST) estimates were derived using the planktonic foraminiferal transfer function FP-12E previously developed by Thompson (1981). The water depths for the cores range from 500 m to more than 4,000 m and thus provide a good opportunity to evaluate the effect of carbonate dissolution on quantitative paleotemperature estimates. The sea surface temperature time series from shallow, well-preserved cores indicate that average winter and summer temperatures during the Holocene were approximately 27 degrees C and 29.5 degrees C, respectively, for both the South China and Sulu seas. These estimates agree well with modern observations. During the last glacial maximum, summer sea surface temperatures were approximately 28.5 degrees C in the South China Sea and 29 degrees C in the Sulu Sea and thus were very similar to the Holocene. In contrast, glacial winter sea surface temperatures are estimated at approximately 21 degrees C for the South China Sea and 24 degrees C for the Sulu Sea. This decrease in glacial winter sea surface temperatures results in a much larger seasonality during the last glacial (5 degrees -8 degrees C) compared to the Holocene (2 degrees C). These seasonal contrasts are much greater than those estimated by Climate: Long-Range Investigation, Mapping, and Prediction Members (1981) for this region of the western equatorial Pacific. Variation in intensity of the monsoon system and surface water exchange rates between these basins and the open ocean are the major factors controlling glacial-interglacial SST fluctuations in the South China and Sulu seas. One factor influencing the accuracy of the SST estimates is the quality of preservation of the planktonic foraminiferal assemblages. Our results demonstrate that depth-dependent increases in dissolution result in systematically cooler SST estimates. This is due to the fact that warm water planktonic foraminifera tend to be more solution susceptible, and as dissolution progresses, the assemblage becomes enriched in the more resistant, cooler water taxa. Since dissolution is more intense during interglacials than glacials in the Pacific, dissolution tends to reduce the amplitude of the glacial-interglacial temperature difference.

AN - 36382756; 4544 AB - PURPOSE: The amending of the fishery management plan (FMP) for American lobsters in the exclusive economic zone (EEZ) along the North Atlantic coast from Labrador to Virginia and along the Outer Continental Shelf from Georges Bank to North Carolina is proposed. The FMP was implemented following the release of the final EIS in March 1983; this final supplement to the final EIS considers an amendment to the FMP which would add additional restrictions to the existing regulations to eliminate or prevent overfishing. The additional restrictions would involve freezing the minimum size limit for all lobsters at the current gauge size of 3.25 inches, thus rescinding the scheduled increase in gauge size mandated by Amendment 2; instituting a new data collection system through a mandatory, uniform logbook with detailed information on landings, fishing effort, and catch rates; establishing a moratorium on new federal vessel permits, with a formal review of the effects of the moratorium in the third year; developing a stock rebuilding program in four newly designated management areas; and revising the overfishing definition so that an area is considered overfished when the fishing mortality rate results in a reduction in estimated egg production per recruit to 10 percent or less of a nonfished population. Under the No Action Alternative, the size limits would increase one sixteenth of an inch as mandated under Amendment 2. POSITIVE IMPACTS: Under the proposed amendment, actions under the FMP would protect the lobster industry from the effects of overfishing and would delay a scheduled increase in the gauge requirements; the spawning stock size and yield per recruit would increase significantly. NEGATIVE IMPACTS: Under the proposed action, quotas on lobster landings could create a temporary economic hardship for existing lobster operations. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

Its purpose is to disseminate data developed from the National Oceanic and Atmospheric Administration's (NOAA) Estuarine Living Marine Resources (ELMR) program (see inside front cover). The ELMR program is conducted by the Biogeographic Characterization Branch of the Strategic Environmental Assessments (SEA) Division. The primary data compiled include the presence, distribution, and relative abundance of each species and the time period it utilizes each estuary. The data and framework presented are illustrative of the nationwide ELMR program. The objective of the ELMR program is to develop a consistent data base on the presence, distribution, relative abundance, and life history characteristics of ecologically and economically important fishes and invertebrates in the nation's estuaries. The data base is divided into five study regions and contains the monthly relative abundance of each species' life stage by estuary for three salinity zones (seawater, mixing, and tidal fresh) identified in NOAA's National Estuarine Inventory (NEI) Data Atlas-Volume I and supplement (NOAA 1985). The nationwide data base contains information for 135 fish and invertebrate species found in 122 estuaries. JF - NOAA/NOS STRATEGIC ENVIRON. ASSESS. DIV., SILVER SPRING, MD (USA). 1994.

In 1988, chloride-depleted (relative to seawater) diffuse fluids with low dissolved metal concentrations (relative to other mid-ocean ridge (MOR) fluids) were sampled over a distance of approximately 10 km along axis. In 1990 and 1991, both high-temperature (>200 degrees C) and diffuse vents were consistently metal- and chloride-enriched. The end-member compositions of high-temperature vents and nearby diffuse vents were very similar. There were small but significant correlated changes in diffuse and high-temperature composition from 1990 to 1991. The large-scale but temporary venting of low-chlorinity fluids over the entire North Cleft segment provides a resolution to the apparent mass imbalance implied by observations of continuous venting of chloride-enriched fluids. It is possible that a volcanic event along the North Cleft segment prior to 1987, for which there is firm geologic evidence, initially caused a boiling event which resulted in the preferential venting of vapor-enriched fluids through 1988, followed by a transition to brine-enriched fluids by 1990. High iron, low sodium, and low Sr/Ca ratios in the high-chlorinity fluids suggest that the brine phase has continued to react and approach reequilibration with an alteration mineral assemblage after the phase separation event. The absence of chloride-depleted fluids from 1990 onward, and the systematics of lithium, boron, and manganese with chloride in the high-temperature fluids from North Cleft suggest that the evolution toward lower chlorinity at Monolith vent from 1990 to 1992 is caused by progressive dilution of a brine with hydrothermal seawater.

The nest was investigated on-site by biologists from Maryland and Virginia, and was generally assumed to be a loggerhead turtle nest because of its proximity to the ocean and isolation from normal nesting grounds for freshwater and terrestrial turtles. The reported nest caused considerable media coverage and controversy, as Maryland is well out of the historical nesting range for marine turtles. Three eggs were sent to the NMFS-Charleston Laboratory for analysis of the egg yolk lipids. These data were used in conjunction with data on the size of the eggs, clutch size, and nest site for species identification purposes. It was determined that the eggs were not those of a marine turtle, but are suspected to be those of a common snapper (Chelydra serpentina). Species identification was not confirmed due to the lack of authentic snapper eggs for comparison. Though snappers have been known to wander far in their search for a suitable nest site, it is unusual to find a snapper nest on a beach in a highly urban area.

The isolated Hawaiian Archipelago contains 132 islands and reefs extending for 2400 km across the North Pacific, from Kure Atoll at the northwestern end (28 degree N, 178 degree W) to the volcanically active island of Hawaii at the southeastern extremity (19 degree N, 154 degree W). The eight large (or main) populated islands in the southeastern portion account for 96% of the coastal benthic habitats suitable for post-pelagic Hawaiian green (honu), Chelonia mydas, and hawksbill (honu-'ea), Eretmochelys imbricata, turtles. Green turtles throughout the chain migrate to breed at French Frigate Shoals at the mid-point of the archipelago (Balazs 1976, 1983). A gradual increase in the number of nesting turtles has been recorded at this site since protection was afforded in 1978 under the U.S. Endangered Species Act. About 350 green turtles nested at French Frigate Shoals during the 1993 breeding season. In contrast, nesting by hawksbills (also protected under the Act) is confined to a few remote beaches exclusively in the main islands, where only small numbers continue to come ashore to lay eggs (Balazs 1978, Balazs et al. 1992).

One of the problems that continues to handicap conservation efforts is the lack of a quick reliable method for aging marine turtles. Length measurements are used to estimate age in other species, but carapace measurements are very often hard to interpret. Measurements are not easily duplicated even if taken by the same investigator and have by nature a high potential for error. The problem is further compounded by longevity and the highly migratory nature of the species rendering the effects of conservation measures inconspicuous for many generations.

Thus, we evaluated the accuracy and precision of a directional sonic telemetry system for application in studies of sea turtle habitat use in Core Sound, North Carolina. We obtained independent bearings from multiple receiver/transmitter stations in each of three habitats of Core Sound: channel, embayment and grassbed. Known geographic locations of stations were obtained from Differential Global Positioning System. Angle errors for all three sites averaged -15 degree plus or minus 7 degree (SD) for an error arc of 14 degree . System bias, including magnetic deviation and hydrophone/compass alignment error, was corrected for before estimating point locations. Median location error was greatest in the channel (41.9 m) and smallest in the grassbed (8.9 m). Location error increased with increasing geometric mean distance between receivers and transmitters, and may have been compounded by variation in depth. Grassbeds range in size from 0.1 to 3189.0 ha in southern Core Sound. Our largest 95% confidence area was 5.7 ha. Almost 70% of the grassbeds in southern Core Sound are smaller than 5.7 ha, but represent less than 2% of the total seagrass area in the sound. Even sea turtle use of these small beds may be detected, given the contagious distribution of the beds. We have shown that directional sonic telemetry is adequate to conduct meaningful habitat use studies which could then be used to designate critical habitat, as required by the Endangered Species Act.

AN - 76532827; 8208212 AB - The measurement of absorbed dose as well as dose distributions (profiles and isodose curves) for small radiation fields (as encountered in stereotactic surgery) has been difficult due to the usual large detector size or densitometer aperture (> 1 mm) relative to the radiation field (as small as 4 mm). The radiochromic direct-imaging film, when read with a scanning laser microdensitometer (laser beam diameter 0.1 mm), overcomes this difficulty and has advantages over conventional film in providing improved precision, better tissue equivalence, greater dynamic range, higher spatial resolution, and room light handling. As a demonstration of suitability, the calibrated radiochromic film has been used to measure the dose characteristics for the 18-, 14-, 8-, and 4-mm fields from the gamma-ray stereotactic surgery units at Mayo Clinic and the University of Pittsburgh. Intercomparisons of radiochromic film with conventional methods of dosimetry and vendor-supplied computational dose planning system values indicate agreement to within +/- 2%.

AN - 62793820; ED369404 AB - After the publication of the Clinton Administration's "The National Information Infrastructure: Agenda for Action," a group of telecommunication specialists were asked to evaluate the proposals in order to broaden the policy discussion concerning the National Information Infrastructure (NII). This collection contains their visions of the nation's future information infrastructure development and their views on how the administration can best achieve its goals. The following papers are included in this volume: "Balancing the Commercial and Public-Interest Visions of the NII" (Lewis M. Branscomb); "Information Infrastructure and Economic Vitality" (Craig I. Fields); "Sustainable Democracy" (Charles M. Firestone and Katharina Kopp); "Open Sesame! How to Get to the Treasure of Electronic Information" (Francis Dummer Fisher); "Competition in Local Telecommunications (Henry Geller); "Extending Universal Service through the NII" (Susan G. Hadden, for the Alliance for Public Technology); "The National Information Infrastructure Report: A Welcome Call to Action" (Allen S. Hammond, IV); "Assembling the Pieces" (Peter W. Huber); "Toward a National Telecommunications and Information Policy: A Development-Based Vision" (Heather E. Hudson); "The Promise of the NII: Universal Service is the Key" (Mary Gardiner Jones); "Networks, Standards, and Intellectual Property: The Fabric of Information Infrastructure" (Brian Kahin); "Building Open Platforms: Public Policy for the Information Age" (Mitchell Kapor); "Public Libraries, the Public Interest, and the National Information Infrastructure (NII): Expanding the Policy Agenda" (Charles R.

Observations from camera tows and submersible dives show that the new flows are all similar in appearance and consist entirely of pillow lava with a mixture of smooth and striated surface textures, suggesting a relatively uniform eruption rate approaching 1 m (super 3) /s at point source vents. The flows vary in size from small patches to large steep-sided ridges and were probably erupted from a dike intruded along the ridge axis because they are aligned along a linear fissure/graben system. Observations at north Cleft show that the physical appearance of new flows changes more rapidly than previously realized and that earlier qualitative dating of young lavas based on sediment cover and glassy surface texture were probably overestimates by an order of magnitude. Sediment accumulation on the lavas is quite variable and locally surprisingly substantial, mainly due to hydrothermal deposits that formed while the lava flows were cooling. Biological vent communities photographed on the new flows in 1989 show that vent animals can colonize new vent sites rapidly but that warm water was still venting only in a few places. Nonvent animals are much slower to colonize the new flows and rates of colonization observed at north Cleft may be useful for making improved age estimates of young (<10 years) lava flows elsewhere. The north Cleft eruption represents about 2% of the estimated average annual volcanic output along the global mid-ocean ridge, implying that many other submarine eruptions are occurring undetected.

Several field seasons of investigations using sidescan sonar, a deep-tow camera system, and the submersible Alvin reveal that about 30 km of the ridge crest is hydrothermally active and/or has experienced recent volcanic and tectonic activity associated with this episode. The most intense hydrothermal activity within this area and all the known high-temperature vents lie along a fissure from which a young sheet flow (YSF) erupted. Extinct chimneys located within 100-200 m on either side of the fissure system represent an older (>100 years) and probably less intense, hydrothermal regime. The bathymetry and the morphology of the YSF suggest that this eruption occurred over a 1-2 km section of the fissure system that forms its eastern boundary and that it flowed to the south. Fields of lava pillars concentrated at the margins of the YSF where lava probably formed when the lava stagnated near the edges of the flow. A comparison of sidescan data sets collected in 1982 and 1987 implies that the YSF was erupted at least 7 months prior to the NPM, consistent with analysis of bottom photographs that suggests that the eruptions of the YSF and NPM were only separated by a few years. The low hydrothermal flux over the NPM relative to the YSF suggests a rapidly cooled underlying heat source beneath the former. We propose that the NPM were erupted from a dike or dikes injected laterally to the north from a magma body lying beneath the YSF. Recent evidence of a decrease in the intensity of the overlying hydrothermal plumes suggests that the system is continuing to cool down. Copyright 1994 by the American Geophysical Union.

Based on the inventories of excess (super 222) Rn, the hydrothermal heat flux was estimated to be 2.7 + or -1.3 GW in 1990. The large uncertainty results from errors in calculating the standing crop of (super 222) Rn, the difficulty in determining the (super 222) Rn to heat ratio, and the problem of entrainment of low-temperature waters into the rising plume. The high-resolution sampling program carried out in 1990 permitted the mapping of apparent plume ages for different sections of the neutrally buoyant plume. About 3 km to the east of the ridge axis there is a sharp gradient in the apparent age of the plume, while to the west the plume appears to be younger. This plume age distribution could indicate a current flow to the northwest during the time this transect was sampled. The mean (super 222) Rn/heat ratios for the high- and low-temperature vent fluids were 0.0017 disintegrations per minute (dpm) g (super -1) degrees C (super -1) and 0.0044 dpm g (super -1) degrees C (super -1) , respectively. The extrapolated end-member concentrations of excess (super 222) Rn in low-temperature vent fluids are a factor of 6 greater than the high-temperature fluids, based on the regressions of excess (super 222) Rn activity and Mg concentration in North Cleft segment vent fluid samples.

We determine the average density of the shallow oceanic crust at the ridge using seafloor gravity measurements and then use these data in conjunction with sea surface gravity observations to construct density structure models. Of 63 seafloor gravity measurements obtained, 42 observations were distributed over the 3-km left-lateral overlapping rift zone (ORZ), located at latitude 45 degrees 03'N, and separating the Juan de Fuca ridge into the Cleft and Vance segments. A 21-measurement seafloor gravity transect was made perpendicular to the ridge strike at latitude 44 degrees 52'N, a region of linear ridge geometry on the Cleft segment. These seafloor gravity measurements, which are sensitive to shallow crustal density variations, were augmented by roughly 800 km of sea surface gravity measurements. Using a bathymetry-Bouguer anomaly analysis of the seafloor gravity data, we determined the average density of the shallow (roughly upper 2 km) oceanic crust at these two locations to be 2630 kg m (super -3) + or - 50 kg m (super -3) . Within the uncertainties of the density determinations, there is no difference between the average shallow oceanic crustal density at the linear Cleft segment and at the Cleft-Vance ORZ. Using the seafloor measurements, we modeled the study area's underlying density to provide constraints on its fine-scale structure. Localized porosity of up to 17% within the upper 500 m of oceanic crust (layer 2A) provide a possible explanation for the observed gravity anomalies at the Cleft segment. Two-dimensional density models of the crust underlying the linear Cleft segment (44 degrees 52'N) show that no deep source is required to explain the topographical asymmetry observed between the east and west sides of the ridge axis. For the Cleft-Vance ORZ, three-dimensional modeling suggests low-density material between the rifts, in agreement with thickened layer 2A from seismic observations. In contrast, layer 2A variations do not explain the low density inferred at the northern end of the Cleft segment since seismic observations suggest a thin layer 2A. The magmatic activity recently observed in this region may have a distinct, deeper source. Copyright 1994 by the American Geophysical Union.

Above the hydrothermal effluent plume, which rose approximately 200 m from the seafloor, > or =90% of the (super 234) Th was dissolved, and the total (super 234) Th activity was in equilibrium with its parent uranium. This is typical of deep water for which the residence time of dissolved (super 234) Th with respect to particle uptake is greater than 200 days. Within the effluent plume, however, as little as 30% of the (super 234) Th was in the dissolved state and the residence time of dissolved (super 234) Th with respect to particle uptake was then of the order of only a few weeks. The flux (J (sub Th) ) of dissolved (super 234) Th to the particle phase was about 300 disintegrations per minute (dpm) cm (super -2) yr (super -1) . The total (super 234) Th was still approximately in equilibrium with U, indicating that the residence time of the (super 234) Th-bearing particles with respect to sinking was greater than 100 days. Particulate P, V, and As, while insignificant above the plume, attained concentrations as high as 60, 0.65, and 0.45 nmol/L within the plume. The particulate [P]/[ (super 234) Th] ratio and the (super 234) Th flux (J (sub Th) ) are used to calculate a removal flux of P resulting from hydrothermal scavenging of approximately 50 mu g cm (super -2) yr (super -1) or approximately 5.0X 10 (super 6) g P yr (super -1) per kilometer of active ridge crest. Similarly, 1.0 X 10 (super 5) g km (super -1) of V and As are removed per year from the water column by hydrothermal scavenging over this region. Extrapolation to a global scale suggests that ridge crest scavenging removes < or =10% of these elements from the ocean. Copyright 1994 by the American Geophysical Union.

Precipitate corrections for Ag, Cd, Cu, Mo, Pb, Sb, and Zn were variable, contributing an average of 20% to total solution concentrations whereas corrections for Co averaged less than 5% and essentially no corrections were required for Fe and Mn. Values for Cu, Co, and Mo in these solutions showed a strong dependence on temperature with sharp decreases in concentrations as temperatures decreased to less than 320 degrees C. In addition, and unlike most other metals studied, all vent fluids from the SJFR were almost completely depleted in Mo relative to seawater values of about 110 nmol kg (super -1) . In contrast to the Cu-Co-Mo group, concentrations of Ag, Cd, Sb, and Pb correlated well with those for Zn and are presumed to follow a distribution that is influenced less by temperature over the 246 to 332 degrees C range encountered in this study and more by the combined chemical processes that control Zn levels along the transport pathway from the deep reaction zone to the vent orifice.

I report here on temporal variability in the intensity and distribution of chronic and event plumes generated by continuous and episodic hydrothermal discharge at two vent fields on the Cleft segment of the Juan de Fuca Ridge. Hydrothermal temperature (Delta theta ) and light attenuation (Delta c) anomalies were comprehensively mapped between 1 and 4 times per year during nine cruises from 1986 to 1991. Intensity of Delta theta and Delta c in the chronic plume overlying the north Cleft vent field showed more variability between years than within a given year. Both Delta theta and Delta c were exceptionally high in 1986, fell to moderate levels during 1988 to 1990, and declined to minimum values in 1991. The chronic plume over the south Cleft vent field varied similarly. Superimposed on the chronic plumes were brief and intense releases of hydrothermal fluid that created event plumes distinguishable by their symmetry and exceptional rise height. Event plumes at the north Cleft field ranged from the 1986 megaplume, with a rise height exceeding 1000 m, to smaller events in 1987 and 1989 with rise heights of approximately 400 m. Chronic hydrothermal heat (660 + or - 277 (1sigma ) MW) and mass (204 + or - 86 (1sigma ) g s (super -1) ) fluxes from the north Cleft field were determined by assuming these fluxes were equivalent to the long-term net advection of a mean cross-section of the vertically integrated Delta theta and Delta c in the plume. This 6-year history of hydrothermal plumes indicates that episodic discharge has been an important component of the recent hydrothermal flux and that the aggregate heat and mass fluxes declined significantly, though not consistently, between 1986 and 1991.

The data set includes observations of focused and diffuse venting fluids and neutrally buoyant plumes formed by chronic and episodic venting. Manganese/heat and iron/heat ratios for plumes from the north end of the Cleft segment were combined with independently determined estimates of plume heat flux to yield annually averaged chronic venting fluxes for Mn of 0.36 + or - 0.17 mol s (super -1) and for Fe of 0.61 + or - 0.34 mol s (super -1) . Over 6 years of plume measurements at North Cleft segment, observed episodic hydrothermal discharge accounted for -15% of the total vented Mn and -35% of vented Fe. The chronic fluxes for Mn and Fe at a second venting center located at the south end of the Cleft segment were estimated to be approximately equal to the fluxes at North Cleft segment. Chronic plumes at North Cleft segment are mixtures of focused and diffuse discharge that contribute heat, Mn, and Fe in variable proportions. Similar examination of South Cleft segment data strongly suggests the presence of an as yet unobserved venting source relatively depleted in Mn and Fe but contributing substantially to the overall heat. Temporal and spatial variations in the concentrations of Mn and Fe and in Mn/heat and Fe/heat ratios for focused seafloor vents were difficult to resolve within complex chronic plumes. Manganese/heat and iron/heat ratios of megaplumes suggest they may have derived from reservoirs of diffuse fluids while smaller event plumes may have formed by different processes and have properties similar to chronic plumes. The accurate assessment of segment-scale hydrothermal fluxes of Mn and Fe requires coordinated measurements of representative seafloor sources and the neutrally buoyant plume that integrates all seafloor discharge.

These data determine the average velocity structure of the upper crust and map the thickness variability of the shallow low-velocity layer, which we interpret as the extrusive volcanic layer. The experiment is unique because a large number of travel times were measured along ray paths oriented at all azimuths within a small (20 km by 35 km) area. These travel times provide evidence for compressional velocity anisotropy in the upper several hundred meters of oceanic crust, presumed to be caused by ridge-parallel fracturing. Compressional velocities are 3.35 km/s in the ridge strike direction and 2.25 km/s across strike. Travel time residuals are simultaneously inverted for anisotropy as well as lateral thickness variations in the low-velocity layer. Extrusive layer thickness ranges from approximately 200 m to 550 m with an average of 350 m. The zone of the thinnest low-velocity layer is within the northern Cleft segment axial valley, in a region of significant hydrothermal activity. Layer thickness variability is greatest near the Cleft-Vance overlapping rift zone, where changes of 300 m occur over as little as several kilometers laterally. These low-velocity layer thickness changes may correspond to fault block rotations in an episodic spreading system, where the low side of each fault block accumulates more extrusive volcanics.

In the rising buoyant plume, >75% of the P, V, Cr, and As scavenging from seawater by hydrothermal precipitates occurs in the first 50 m above the vent. Cu and Zn are most enriched in buoyant plume particles collected from the first few meters above the vent. However, the degree of enrichment decreases very rapidly with increased height above the vents due to sedimentation of the more dense Cu- and Zn-rich sulfide phases. Using the plume data, coupled with the results of our analysis of sediment trap samples, we estimated that more than 99% and 99.9%, respectively, of the total hydrothermal Fe and Mn produced at the vent field are transported beyond the vent field and dispersed in the open ocean.

Indexed XRD lines are tabulated: strongest lines 2.863(100), 2.653(50), 2.388(50), 2.771(40), 2.272(30), 1.832(30) Aa; a 9.068, b 17.992, c 14.486 Aa, beta 104.86 degrees ; space group P2 (sub 1) /c, Z = 2. The structure may be viewed as being composed of layers of vertex-sharing TO (sub 4) tetrahedra (T = Si,Be,Zn) alternating with layers of vertex- and edge-sharing CaO (sub 8) bicapped trigonal prisms and MnO (sub 6) octahedra, the layers being (102). The TO (sub 4) groups and CaO (sub 8) -MnO (sub 6) groups share vertices with one another across the layer boundaries to form the three-dimensional structure. Within the layers of tetrahedra, the TO (sub 4) groups form a network of 4-, 5- and 8-membered rings. The P2 (sub 1) /c space group may only represent an average structure, the true structure having lower symmetry due to ordering of Zn and Be on separate sites. The name is for Dr. Samuel Fowler (1779-1844), the pre-eminent figure in the Franklin mining district.

The mitogenic response of English sole leukocytes was assessed for a variety of mitogens. In vitro culture conditions for English sole leukocytes that would maintain cellular viability and allow leukocytes to proliferate were initially determined with an undefined medium. Factors that were varied to create an effective mitogen assay included mitogen type (pokeweed mitogen, concanavalin A, phytohemagglutinin, and lipopolysaccharide), mitogen concentrations, incubation time and temperature, medium supplementation, and number of leukocytes per culture. A leukocyte concentration of 1 10 super(7) leukocytes/mL provided for the greatest proliferation; cell concentrations above or below this level resulted in less proliferation. A higher degree of proliferation occurred when the leukocytes were incubated with fetal calf serum than with heatinactivated autologous plasma. It was confirmed that leukocytes were responsible for proliferation of the Splenic whole-cell population in response to mitogens. Pokeweed mitogen and lipopolysaccharide were able to stimulate English sole leukocytes to proliferate at ITC. However, phytohemagglutinin and concanavalin A were generally unable to induce cellular proliferation. The ability of pooled leukocytes to produce a tridirectional MLR was also examined once effective culture conditions were determined via the mitogen assay. Mixed leukocyte reactions were negative or borderline positive when leukocytes from three English soles were cultured.

Sea turtle meat and eggs were also important foods for the early settlers. Turtling was undoubtedly one of the first commercial fisheries in the southeastern United States not only because sea turtles were abundant, but also because of the relative ease of capture when laying eggs on deserted beaches. Also, no boats, nets, or other expensive equipment were needed, and the turtles could be easily kept alive until sold. The commercial fisheries for the now threatened and endangered species of sea turtles in U.S. waters have been neither adequately described nor analyzed in detail. In this paper, I describe the U.S. sea turtle fisheries and summarize the commercial sea turtle landings reported in Federal fishery documents for the continental United States, Puerto Rico, and Hawaii. These important baseline fisheries data on threatened and endangered species of sea turtles provide considerable insight into the sociology and economics of the U.S. sea turtle fishery.

Traditional measures of nominal effort can lead to biased performance measures since fishing effort is a multidimensional concept not readily captured by nominal measures. This paper evaluates the source of growth in catch over time according to its constituent components - the growth accounting framework - to measure trends in catch, nominal and effective effort, and productivity or fishing power. An empirical study of the US Pacific coast groundfish trawl fishery indicates that traditional measures of effort and fishing power can be biased and highlights the relative importance of growth in productivity or fishing power as an often overlooked and perhaps the most important source of growth.

The cause of this die-off is unknown but current hypotheses point to environmental stress making this seagrass susceptible to disease. The potential exists for colonization and recovery of these die-off patches but the sequence of events and the persistence of the recovery have not been evaluated. Based on an existing model that represents theoretical successional steps toward the Thalassia climax, four habitat types were sampled in each of two basins of western Florida Bay. Data demonstrated a high potential for recovery of the denuded die-off patches. The alga Batophora oerstedi is the first colonizer with replacement by other algal species and subsequently Halodule wrightii and eventually Thalassia. Under the existing conditions of high resuspended carbonate sediment and biological turbidity, which are thought to be secondary responses of the system to the die-off of seagrasses, persistence of the colonizing habitats and the climax community itself is tenuous.

Subsequent visits in 1993 revealed that the sample sites were devoid of seagrasses.

Ophiura sarsi and American plaice were sampled during a 1-yr period (1985-1986) from a site of 148-156 m depth. The bimodal size-frequency distributions of the O. sarsi population were dominated by small individuals with disk diameters between 2 and 11 mm, and with estimated growth rates, based upon the modal progressions from the persistent 1985 year class, of ) 4 mm per year. Larger individuals () 15-25 mm) were generally less numerous. These older brittle stars, which formed the right-hand peaks of the size-frequency distributions, displayed little noticeable growth, which suggests that these peaks were comprised of multiple cohorts. Recruitment to the population appeared to be continuous, due to the occurrence of 1 mm or smaller brittle stars throughout most of the year. The strong presence of 1 mm or smaller O. sarsi in January, 1986 indicated a major recruitment event. A survey of the reproductive condition of the gonads showed evidence of continuous but seasonally variable reproduction, with the major spawning centered around January. O. sarsi was the major dietary constituent of the American plaice, occurring in at least 65% of the fish stomachs throughout the year. Plaice consumed the most abundant size classes of O. sarsi in the population, with disk sizes between ) 4 and 10 mm. These brittle stars were of low caloric value, yet the more nutritious, older brittle stars were not eaten in significant numbers by even the largest plaice. The high proportion of small, energy-poor O. sarsi found in the plaices' diet might be the result of their greater abundance of accessibility at this site.

Summit depth, harvest area, amount of shallow habitat, and latitude were considered in relation to pre-exploitation research catch rates and 6 years of commercial fishery landings. A threshold between lobster production and the depth of bank summit was observed; banks with summits deeper than 30 m yielded few lobsters. The effect of benthic habitat relief was then examined for three selected, bathymetrically similar banks, two commercially productive and one unproductive. Percent cover of habitat variables with characteristic relief such as sand, algae, and coral outcrops were measured on each of the banks during 70 scuba dives. Juvenile lobster stages were found significantly associated with habitat scale. The nonlinear relationship indicated both high and low extremes in relief yield poor catch per unit of effort (CPUE). Only the variable intermediate relief (5-30 cm) was associated with high sublegal lobster CPUE. The two productive banks had much more benthic relief at this scale than did the unproductive, suggesting that the abundance of intermediate relief habitat represents a bottleneck to adult lobster production.

Males born in 1987 tended to weigh less at age 3 and 4 yr than those born in other years. Weights of individuals at ages 2, 3, and 4 yr were significantly correlated with their weights as pups (P < 0.05). Weights at ages 2 and 3, 3 and 4, and 4 and 5 yr were significantly correlated (P < 0.001), although weight changes with age were highly variable. Data indicate that larger than average male pups born during 1987-1990 were more likely to survive, but this effect was less evident than among pups born during 1960-1965 when average pup weights were lower.

Spawning began as early as May when eggs and larvae occurred off Cape Hatteras, advanced northward with time, peaked in July when eggs and larvae occurred as far north as Cape Cod, and ended in late August. Unlike earlier studies that argue for multiple and distinct spawning seasons, this 11-year study concludes that spawning in the NCSE represents the continuation of a protracted season that begins in late winter in slope waters off the southeastern United States and progresses northward with time. Results add to a growing block of evidence that supports a unit stock designation for the bluefish population along the east coast of the United States.

Pupping, lactation, weaning, and molting were directly observed, while mating was rarely observed and was, therefore, inferred from the occurrence of mounting injuries and from adult male and female association patterns. Pooled birth rates during the study period were 0.544 for all adult-sized females and 0.675 for females parous in earlier years. For parturient females, pupping peaked in late March and early April, weaning in May, mounting injuries in May and June, and molting in July. For non-parturient females, the median mounting injury and molting dates occurred 17 and 28 days earlier, respectively. Pupping date set the timing of subsequent events in the annual cycle, but the timing of those events was adjusted by loss of the pup or poor physical condition of the female. Individual pupping patterns varied widely. The mean interval for births in consecutive years was 381 days; females that pupped in consecutive years gave birth later each season. Conversely, females who skipped a year or more gave birth earlier their next pupping season.

Klinowska (1991) states that "the stock in the northeast Pacific is believed to be near extinction, possibly represented by no more than a few individuals." On 24 March 1992, Southwest Fisheries Science Center observers encountered on North Pacific right whale at 32 degree 14'N, 118 degree 42'W, while conducting an aerial census for marine mammals. This location is 70.4 km southwest of the southeast tip of San Clemente Island, and 47 km southeast of Cortes Bank. The water depth at this location is ) 1,700 m. Diagnostic features observed that allowed positive identification of this right whale were as follows: body black, back smooth without dorsal fin, upper jaw arched and lower lip strongly bowed, numerous callosities on the head and lower jaw, V-shaped blow, and wide tail flukes.

The cause of this decline is not known. A life table for the northern sea lion was calculated assuming that life spans follow a Weibull distribution. Samples of northern sea lions taken in the vicinity of Marmot Island, Alaska during 1975-1978 and 1985-1986 indicate that the average age of females older than 3 yr increased about 1.55 yr (SD = 0.35 yr) while the population was declining at about 5% per year. Fecundity rates decreased by 10% over the same period, but the decrease was not statistically significant (Calkins and Goodwin 1988). Possible causes of the population decline and the change in age structure were examined by writing the Leslie matrix population equation in terms of changes in juvenile and adult survival rates and fecundity, and examining the short-term behavior of the trajectories of the average age of adult females, total number of females, and total number of pups with respect to those changes in the vital parameters. From the observed rate of declines of adults and the changes in average age of adult females and fecundity, estimates of the changes in adult and juvenile survival were calculated; estimates of the standard deviations of these changes were estimated via a bootstrap procedure. One purpose of this exercise is to aid in setting priorities for research for determining the cause of the decline. An explanation for the observed declines in numbers of adult sea lions consistent with the observed fecundity rates, a rate of decrease of 5% in the number of adults, and the corresponding increase in average age (of females age 3 yr and older) was a 10%-20% decrease in the survival of juveniles (age 0-3 yr) coupled with an insignificant change in adult survival (0.03%, SD = 1%).

Ribonucleic acid (RNA) and deoxyribo-nucleic acid (DNA) content during embryogenesis were compared to temperature and embryo age. Hatching time, larval size, yolk-sac volume, and RNA content at hatching were inversely related to incubation temperature. DNA content and RNA/DNA ratios of larvae were similar on the day of hatching at all experimental temperatures. The energetic reserves available during embryonic and prolarval development are enhanced by lower incubation temperatures. Prolarvae reared at 12 degree C had high rates of yolk utilization and initial growth, but experienced reduced growth and a decline in DNA content prior to feeding initiation. The effects of food availability on nucleic acid content and RNA/DNA ratios of first-feeding walleye pollock were determined. Mean RNA and DNA content and RNA/DNA ratio of fed larvae were significantly higher than those of unfed larvae after 2 days. Starvation of larvae that had successfully initiated feeding resulted in a rapid decline of RNA content (and RNA/DNA ratio) accompanied by a slower decline in DNA.

Data collected during more than 6,500 hours of monitoring at 106 structure removals in 1992 provided information on sea turtle distribution. Eighteen individuals were observed including 10 loggerheads, 2 leatherbacks, 1 hawksbill, and 5 unidentified sea turtles. The observation rate (individuals per monitoring hour) of sea turtles was about 30 times higher during aerial surveys than during day or night surface surveys.

Benthic prey were collected during 1983-1985 from seven areas in the Bight apex. These areas were selected because they span a range of habitat quality conditions in the Bight apex, and fish dietary information was available. Another area outside of the Bight apex was used as a reference, since it was expected to be affected minimally by waste disposal. Benthic taxa collected from each area were selected because of their common use as prey in the results of prior or concurrent fish and American lobster diet studies. There were no major changes in disposal practices within the Bight apex during the sampling period. Only sub-adult (<2 cm carapace width) Atlantic rock crabs, Cancer irroratus, were sampled as they were the size usually eaten and were assumed to be less motile and most associated with each collection area, so that metal concentrations found would reasonably reflect overall exposure within each area.

The Dover sole, Microstomus pacificus, differs from the other local flatfish species by undergoing an extensive ontogenetic vertical migration, occupying all depth zones at different life stages, and having its maximum spawning biomass in the oxygen minimum zone between 600 and 1000 m. Size-activity relationships and depth-activity relationships for the glycolytic enzyme lactate dehydrogenase (LDH) and for two enzymes associated with aerobic metabolism, malate dehydrogenase and citrate synthase (CS), were examined in white-muscle tissue of shallow-living, deep-living and ontogenetically-migrating species. Scaling coefficients (b) for weight-specific enzyme activity (log activity) = a + b (log wet weight), varied in sign as well as magnitude for fishes living at different depths. In the shallow-living California halibut Paralichthys californicus, LDH scaled positively (0.39) and CS scaled negatively (-0.15) with size, a pattern observed previously for most shallow-water fish species. The permanently deep-living species, the deep-sea sole Embassichthys bathybius, differed in that both LDH and CS scaled strongly negative (-2.0 and -1.5, respectively). For the ontogenetically migrating Dover sole Microstomus pacificus, there was a shelf-slope transition. For the shelf specimens ( less than or equal to 200 m), LDH scaled positive (0.11) and CS negative (-0.29) and for the slope specimens ( greater than or equal to 400 m), LDH scaled negative (-0.65) and CS strongly negative (-0.63). Rex sole, Glyptocephalus zachirus, showed a similar shelf-slope transition. Intraspecific depth-enzyme activity differences were not incremental, but changed abruptly between the continental shelf stations (100 to 200 m) and the continental slope (400 to 1400 m). Based on comparisons with laboratory-maintained individuals, the decline in the metabolic capacity of the white muscle of Dover sole is a phenotypic response to the low food and oxygen conditions of the continental slope. Contrary to expectation, anaerobic capacity (LDH activity) decreased in response to low oxygen conditions, suggesting that in a permanently hypoxic environment such as the oxygen minimum zone the metabolic strategy may be to not incur an oxygen debt that would be difficult to pay back.

Chemical oxygen demand (COD) was significantly reduced by bubbling ambient air through the sediment for 6 to 10 h. Combined treatments lowered the sediment oxygen uptake to a level which was not statistically different (p < 0.0001) from 0.2 mu m filtered seawater. The described method is useful for sufficiently reducing sediment oxygen consumption (BOD and COD) to measure respiration of infaunal organisms, including ophiuroids, bivalves and polychaetes, in a more natural, buried setting.

Prior to 1960, the two stocks were fished exclusively by the United States. During the 1960s, marked increases in exploitation occurred due to the development of Canadian and distant-water fisheries on Georges Bank. Total landings from the two stocks increased from 14 400 t in 1960 to 57 500 t in 1966, but subsequently declined to 30 000 t in 1976. Under extended fisheries jurisdiction - enacted in 1977 by both the USA and Canada - landings and stock sizes initially increased and a record-high catch (71 000 t) was attained in 1982. However, during the late 1980s and early 1990s, fishing effort and fishing mortality also increased to record-high levels, resulting in marked reductions in spawning-stock size. Research vessel indices, commercial c.p.u.e. indices, and VPA results all indicate that biomass levels in both stocks are now at record-lows. Although it is clear that fishery-induced perturbations have had a major impact on the Georges Bank and Gulf of Maine stocks, environmental and biotic influences may also have affected the stocks. These influences are not easily discernible, given the magnitude of the fishery-induced changes. Biophysical processes appear to be extremely important during the first year of life of cod and affect growth, mortality, and year-class strength. These processes are reviewed and discussed in relation to their impacts on various life history stages of cod. Current and future research studies aimed at differentiating environmental from fishery-related factors affecting recruitment and abundance of cod in the Georges Bank-Gulf of Maine region are discussed.

This is presumably due to a reduction in the thickness of the diffusion boundary-layer which allows for a higher carbon availability on the plant surface. Blades of the seagrasses Thalassia testudinum and Cymodocea nodosa exposed to different current velocities under controlled laboratory conditions, showed increased photosynthetic rates with increasing flow only at low current velocities (expressed as blade friction velocities, u sub(*)). Carbon saturation of photosynthetic processes occurred at a relatively low u sub(*) level (0.25 cm s super(-1)) for T. testudinum collected from a calm environment compared to C. nodosa (0.64 cm s super(-1)) collected from a surf zone. No further enhancement of photosynthetic rates was observed at higher u sub(*) levels, suggesting limitations in carbon diffusion through the boundary layer below critical u sub(*) levels and possible limitations in carbon fixation by the enzymatic system at higher u sub(*) levels. These results, as well as those of previous theoretical studies, assumed the flow on the immediate seagrass-blade surface to be hydrodynamically smooth. The presence of epiphytes and attached debris causes the surface of in situ seagrass blades to be exposed to flows ranging from smooth to rough-turbulent. As a consequence, the boundary-layer thickness on moderately epiphytized blades under medium to high flow-conditions is not continuous, but fluctuates in time and space, enhancing carbon transport. In situ u sub(*) levels measured directly on blades of seagrass indicate that T. testudinum and C. nodosa can be exposed to conditions under which the boundary layer limits photosynthesis during short periods of time (milliseconds) during low-energy events. As waves cause the thickness of the diffusion boundary-layer to fluctuate constantly, carbon-limiting conditions do not persist for prolonged periods. JF - Marine biology.

Cytochemical measures of lysosomal responses in the digestive cells using automatic image analysis AN - 16628843; 3668120 AB - Lysosomal responses in the digestive cells of Mytilus edulis from 9 sites in Puget Sound, Washington, USA, with varying degrees of sediment contamination were measured using automatic image analysis. Mussels from urban-associated sites (areas with elevated sediment concentration of anthropogenic contaminants such as PAHs, PCBs, DDTs, and toxic elements) showed pathological changes in the lysosomes (reduced lysosomal labilization period, reduced lysosomal stability and increased N-acetyl beta -hexosaminidase activity), enhanced lipofuscin deposition and increased accumulation of lysosomal and cytoplasmic unsaturated neutral lipids. Morphometric measures of growth showed that mussels were generally smaller in size and that somatic tissue weight relative to shell length was lower in mussels from urban-associated sites relative to those from minimally contaminated sites. Highly significant correlations were observed between concentrations of tissue PAH, PCB, and selected toxic elements (measures of anthropogenic exposure) and lysosomal labilization period. Pathological alterations in the lysosomal system of mussels from the urban-associated sites were probably induced by the high tissue concentrations of organic and inorganic contaminants rather than as a result of potential confounding biotic (spawning stress) or abiotic (temperature, salinity and food availability) factors. The results show that cytochemical measurement of lysosomal responses combined with automatic image analysis have the potential to be used as sensitive, accurate and rapid techniques for assessing the biological impact of environmental contaminants in mussels in the near coastal environment.

Home ranges extended from 954 to 28833 km super(2) while core areas varied from 89.6 to 4,279 km super(2). Core areas included several petroleum and gas structures that may have been visited on a daily, weekly or monthly basis. Average submergence times of loggerheads ranged from 4.2 min in June to 171.7 min in January. The number of submergences per day was inversely proportional to duration of submergences per day. Loggerheads spent, on the average, over 90% of their time under water in any given season. Bottom depth location of the loggerheads was significantly correlated to Galveston's mean air temperature (-0.56 < r < 0.28) and mean sea surface temperature (-0.72 < r < 0.25). Correlation was higher (-0.58 < 4 < 0.60) when temperatures were regressed against distance from shore. Mean swimming speeds of these loggerheads were from 0.4 to 1.4 km/h, with over 95% of the values < 5 km/h.

Increased use of atrazine in the 1970s coincided with a decline in the abundance of Zostera marina L. (eelgrass). Groundwater surveys have found atrazine in concentrations that may affect eelgrass growth and survival. The effects of atrazine in groundwater discharges on the growth of eelgrass through root-rhizome exposure were examined in laboratory systems. A long term, dynamic, groundwater simulation study was conducted with atrazine concentrations ranging from 0.0 to 2.5 mg/l. No significant effects on chlorophyll content, growth or survival were detected. A static root-rhizome exposure experiment was conducted using split chamber exposure systems to verify these results, atrazine concentrations were increased by an order of magnitude. Neither mortality nor significant effects on plant growth were detected (maximum atrazine concentration 7.6 mg/l. A static, whole plant exposure experiment was conducted, and mortality was observed at atrazine concentrations of 1.9 mg/l and above. This work suggests that eelgrass is not susceptible to atrazine through root-rhizome uptake, and that atrazine exposure via groundwater seepage did not cause the declines in eelgrass abundance and distribution.

A major milestone was reached in advancing toward a more ecologically based management practice when the majority of coastal nations of the world endorsed the declaration made at the United Nations Conference on Environment and Development (UNCED) in 1992, to prevent, reduce, and control degradation of the marine environment, so as to maintain and improve its life-support and productive capacities; develop and increase the potential of marine living resources to meet human nutritional needs, as well as social, economic, and development goals; and promote the integrated management and sustainable development of coastal areas and the marine environment. The scientific framework in support of the UNCED objectives is now emerging from a series of regional efforts aimed at cross-sectoral integration of research, monitoring, and assessments conducted to mitigate stresses on coastal ecosystems from toxic effluents, habitat degradation, nutrient loadings, harmful algal blooms, aerosol contaminants, and losses of living resources from pollution and overexploitation. Discipline-oriented ecological studies can contribute more toward achievement of resource sustainability when they are conducted within a framework of science at the level of organization that is multidisciplinary and focused on populations, habitats, and ecosystems at large spatial scales. Primary, secondary, and tertiary driving forces of variability in biomass yields are examined for several large marine ecosystems, along with observations on changing states of 'health' of the systems. Marine resource problems underscored by UNCED are being addressed. Post-UNCED large marine ecosystem-scale programs for advancement toward resource sustainability, ecosystem health, and economically viable biomass yields are now being implemented. The programs are being supported by international agencies as part of an effort to couple recent advances in ecological monitoring, management, and stress mitigation strategies from the more developed countries, with the lesser developed coastal countries around the margins of the ocean basins.

AN - 15221917; 4427 AB - PURPOSE: The implementation of a management plan to protect the habitat of late-successional-forest- and old-growth-forest- related species within the range of the northern spotted owl is proposed for lands managed by the Forest Service (FS) and the Bureau of Land Management (BLM) in the Pacific Northwest and northern California. Ten action alternatives developed by the Forest Ecosystem Management Assessment Team are considered in this final supplement to the final EIS of January 1992 supplementing a final EIS issued by the FS for the Pacific Northwest region, and six draft EISs issued by the BLM in August 1992 for individual districts in Oregon. The No Action Alternative was considered unreasonable and could not be implemented. Under the preferred alternative (Alternative 9), a management direction would be established that corresponds with the plan announced by President Clinton in July 1993. Approximately 7.32 million acres of forest reserved by Congress as national parks, wildlife refuges, and other specially designated areas, would be retained; another 7.43 million acres would be managed as late-successional reserves. Some level of silvicultural treatment would be permitted in stands less than 80 years old in the West in order to accelerate the development of old-growth-habitat characteristics, but all actions would require review by the Regional Ecosystem Office. The salvage of dead trees would generally be limited to areas where catastrophic losses exceeded ten acres in the East. Approximately 1.48 million acres would be managed as adaptive management areas; each of these areas would have a different emphasis in its prescription, such as maximizing the amount of late-successional forests or improving riparian conditions through silvicultural treatments. Ten areas of federal land ranging in size from 92,000 to 500,000 acres have been identified as adaptive management areas. Approximately 2.63 million acres would be managed as riparian reserves, providing a buffer along all streams, wet areas, ponds, lakes, and unstable and potentially unstable areas. Finally, roughly 3.98 million acres would be managed as matrix areas, in which some levels of timber harvesting and other silvicultural treatment would be permitted. POSITIVE IMPACTS: The protection of old-growth habitat under the preferred management scheme would ensure the continued existence of the endangered northern spotted owl, the marbled murrelet, and other species dependent on late-successional forest and old-growth forest. The proposed limitations on timber harvesting would benefit the watershed, fisheries, and soils. Similarly derived benefits would redound to recreational resources, cultural resources, and Native American religious sites. NEGATIVE IMPACTS: Some old-growth forest stands would be harvested under the preferred alternative. A reduction in harvest activity would take place, however, which would cause the loss of jobs and income and could threaten the economic vitality of timber-dependent communities.

AN - 36409106; 4425 AB - PURPOSE: The amending of the fishery management plan (FMP) for the harvest of sablefish off the coasts of Washington, Oregon, and California is proposed. The amendment would establish an individual quota program to cover the harvest of sablefish by vessels with groundfish limited-entry permits for longline and fishpot gear. The harvest of sablefish by trawl gear in the license limitation fishery or longline, fishpot, and other gear by unlicensed vessels in the open access fishery is not covered by the proposed individual quota program. The fixed-gear sablefish individual quota program designed by the Pacific Fishery Management Council would allocate sablefish quota share, which is a percentage of the total annual harvest guideline, to persons based primarily on catch history. Each year, holders of quota share would be allocated an amount of sablefish individual fishing quota, which is an amount of sablefish pounds for the year based on the amount of quota share held, which could be taken anytime during the fishing season. To be affected by the quota, a vessel or a person must have recorded at least one landing of sablefish or groundfish with fixed gear between August 1, 1988 and November 13, 1991. A quota share (a percent of the total annual harvest guideline) would be allocated to owners of ""A'' permits based on catch history extending back to January 1, 1984. Each year holders of quota share would be allocated an individual quota representing the pounds of sablefish catchable in that year. After a quota share is initially issued, anyone eligible to own a U.S. documented fishing vessel would be eligible to purchase or otherwise acquire a quota share from one of the initial recipients. These eligible parties would include, but not be limited to, vessel operators, crew members, processors, and banks; foreign-controlled entities would not be eligible. Caps would exist on the amount of quota controlled by a single person or used on a single vessel. Persons with individual fishing quotas could be required to be aboard the vessel when the sablefish are caught. A small amount of unused individual quota could be carried over from one year to the next. The monitoring and enforcement of individual quotas could entail restrictions on where and when vessels might land sablefish, requirements for advanced notice of landings, and other rules designed to ensure compliance with the program. The estimated annual costs of the enforcement program range from $450,000 to $575,000, and the estimated start-up costs of the administrative program are approximately $2.0 million. The only other alternative under consideration is the status quo arrangement, allowing common access to sablefish among fixed gear license holders. POSITIVE IMPACTS: Under the proposed amendment to the FMP, the sablefish industry would be protected from the effects of overfishing. Processing and marketing costs would be lowered by giving processors more control of scheduling. NEGATIVE IMPACTS: An individual quota system could increase the discard rate and discard mortality because of an interest in retaining only high-grade fish and a shift from fixed gear to longline gear. Groups or individuals who did not qualify for quota allocation would be put at a permanent disadvantage in the market; affected parties could include foreign interests, vessel owners denied an initial allocation, and corporations and partnerships owning processors.

It was found that in 1990, 14 percent of the population 5 years and older spoke a language other than English at home, as contrasted with 11 percent in 1980. Languages spoken most commonly at home in descending order of percentage, were: Spanish; French; German; Chinese; Italian; Tagalog (Pilipino); Polish; Korean; Vietnamese; Portuguese; Japanese; Greek; Arabic; Hindi (Urdu); and Russian. For these languages, total numbers spoken in 1980 and 1990, and percentage changes, are charted. A map of the United States indicates percentages of the population in each state that speak a language other than English at home. It was found that slightly more than half of all non-English-speakers in the United States reside in three states: California; Texas; and New York. Data are also provided on the distribution of English language skills (speaks English not at all, not well, well, or very well) within the population that speaks a language other than English at home.

AN - 36412346; 4446 AB - PURPOSE: The implementation of a fishery management plan (FMP) for corals and reef-associated plants and invertebrates in state and federal waters off Puerto Rico and the U.S. Virgin Islands is proposed. The plan would cover over 100 species of coral (including stony corals, sea fans, and gorgonians), and 60 species of plants (including seagrasses) and invertebrates (including live rock, a rock substrate that supports diverse invertebrate life forms). Many of these resources are being harvested by the relatively new and expanding fishery for the marine aquarium industry. The corals and coral reefs are of enormous value for the reef communities that they support, for their physical capacity to protect coastlines, and for the aesthetic value. Under the proposed plan, regulations for management would prohibit the harvesting or possession of stony corals, sea fans, gorgonians, and certain species associated with live rock, live or dead, except for legally permitted research, education, and restoration; prohibit the sale or possession of any prohibited species unless fully documented as to point of origin; prohibit the use of chemicals, plants, or plant-derived toxins, and explosives to harvest organisms, except for legally permitted research, education, and restoration programs; limit the harvesting of other invertebrates to hand-held dip nets, slurp guns, and hand and other non-habitat-destructive gear, except for legally permitted research, education, and restoration programs; require invertebrate harvesters to obtain permits and report harvesting results; and establish a marine conservation district south of St. John, where all harvesting would be prohibited. Under the FMP, the states would also be directed to establish permitted anchoring sites in coral reef areas; identify habitats of critical concern; expand data collection efforts; regulate diving operations; and regulate the discharge of untreated sewage and petroleum products into coastal waters. POSITIVE IMPACTS: Under the proposed FMP, the reef and seagrass habitats around Puerto Rico and the U.S. Virgin Islands would be protected. In addition to being a valuable biological resource, these habitats have commercial, medical, and recreational importance; significant damage to reef habitats would endanger commercial fishing opportunities in the area. NEGATIVE IMPACTS: Although the conservation measures would eventually benefit the commercial fishing industry, aquarium fish industries would experience increased operating costs once the proposed gear restrictions were in place.

AN - 36406428; 4439 AB - PURPOSE: The amending of the fishery management plan (FMP) for the American lobster is proposed in the exclusive economic zone (EEZ) along the North Atlantic coast from Labrador to Virginia and along the Outer Continental Shelf from Georges Bank to North Carolina. The proposed amendment would be designed to eliminate or prevent overfishing by adding additional restrictions to the existing regulations. Three alternatives, including a No Action Alternative, are considered in this draft EIS. Under the proposed action, the additional restrictions would involve freezing the minimum carapace size limit for all lobsters at the current gauge size of 3.25 inches, thus rescinding the scheduled increase in gauge size mandated by Amendment 2; instituting a new data collection system through a mandatory, uniform logbook with detailed information on landings, fishing effort, and catch rates; establishing a five-year moratorium on new federal vessel permits, with a formal review of the effects of the moratorium in the third year; instituting a new requirement for an operator's permit for operators of fishing vessels engaged in the fishery; requiring several categories of federal vessel permits and limits on lobster landings according to the permit category; developing a stock rebuilding program, addressing all segments of the harvesting sector, in response to an assessment that the stock is overfished, in four newly designated management areas; and revising the overfishing definition so that an area is considered overfished when the fishing mortality rate results in a reduction in estimated egg production per recruit to 10 percent or less of a nonfished population. Under the two other alternatives, the minimum size requirements would increase beyond the 3.25 inch limits. POSITIVE IMPACTS: Under the proposed amendment to the FMP, the lobster industry would be protected from the effects of overfishing. A scheduled increase in the gauge requirements would be delayed. Significant increases in the spawning stock size and yield per recruit should result. NEGATIVE IMPACTS: The proposed quotas on lobster landings could create a temporary economic hardship for existing lobster operations. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

AN - 76793799; 7952943 AB - The lack of rapid, high throughput assays is a major obstacle to many aspects of research on marine phycotoxins. Here we describe the application of microplate scintillation technology to develop high throughput assays for several classes of marine phycotoxin based on their differential pharmacologic actions. High throughput "drug discovery" format microplate receptor binding assays developed for brevetoxins/ciguatoxins and for domoic acid are described. Analysis for brevetoxins/ciguatoxins is carried out by binding competition with [3H] PbTx-3 for site 5 on the voltage dependent sodium channel in rat brain synaptosomes. Analysis of domoic acid is based on binding competition with [3H] kainic acid for the kainate/quisqualate glutamate receptor using frog brain synaptosomes. In addition, a high throughput microplate 45Ca flux assay for determination of maitotoxins is described. These microplate assays can be completed within 3 hours, have sensitivities of less than 1 ng, and can analyze dozens of samples simultaneously. The assays have been demonstrated to be useful for assessing algal toxicity and for assay-guided purification of toxins, and are applicable to the detection of biotoxins in seafood.

AN - 76792371; 7952945 AB - Domoic acid (DA) was first reported in mussels from Prince Edward Island, Canada, in 1987. It reappeared in anchovies and pelicans from Monterey Bay, California, in 1991. Later that year, domoic acid was found in razor clams and Dungeness crabs along the Washington and Oregon coasts. Since the initial outbreak, a variety of analytical methods for the detection of this neurotoxin have been developed. Here, we describe a modification to the solid phase extraction (SPE) clean-up step in Quilliam's HPLC-UV method (1991: NRCC No. 33001). The standard 10% acetonitrile (MeCN) wash and 0.5M ammonium citrate buffer (ACB) in 10% MeCN (pH = 4.5) eluting solution have been replaced with a 0.1M sodium chloride (NaCl) in 10% MeCN wash and a 0.5M NaCl in 10% MeCN eluting solution. This modification allows the analysis to work equally well on both clam and crab viscera and meat. Chromatograms of visceral samples no longer contain interfering or late eluting peaks; and all chromatograms are free of the large solvent peak tailing associated with the ACB eluent. The newly modified method allows for an improved and more versatile domoic acid analysis.

There are many areas as large as the state of Oklahoma where no depth measurements are available. Satellites carrying radar altimeters have measured the shape of the ocean along tracks only 3-4 km apart, and from these data we can make very accurate and high resolution maps of the marine gravity field. The gravity field mimics the seafloor topography in the 15-160 km wavelength band if sediment cover on the ocean floor is thin. Long-wavelength (greater than 160 km) topography is isostatically compensated and is not correlated with the gravity field. In addition, the satellite gravity field and the available depth measurements were used to determine the correlation between gravity and the seafloor topography. By applying this correlation to the gravity field we predict seafloor topography in the 15-160 km wavelength band. This topography is combined with a long-wavelength component estimated directly from ship depth measurements. The result reveals many new features and is within + or - 100m of actual depths in many cases. The GEOSAT gravity data has been used in combination with this algorithm to produce a 36" x 48" color poster. A color, polar stereographic view of the Predicted Seafloor Topography is now available from the National Geophysical Data Center. The image is also available for viewing on Mosaic. The digital data from which this color image was generated is available from the National Geophysical Data Center. The Predicted Seafloor Topography is an inferred data set and is not true bathymetry. It is, however, the best estimate of seafloor topography available resulting from satellite gravity data and actual ship depth measurements. This data is intended for scientific research and should not be used for navigational purposes. Additional software is required in order to manipulate the data or produce your own graphic images. The coverage for this data base is 30 degrees S - 70 degrees S. The grid spacing is 3 minutes of longitude by 1.5 minutes of latitude (7200 x 1600). The present format is a GMT/netCDF binary grid file. In this format the file is about 47 megabytes.

In 1992, Chile's economy grew 9.7 percent, while unemployment fell to under 5 percent. Strict fiscal discipline, increased exports, growth in consumption, privatization of state-run businesses, and the opening of the economy to imports stimulated this growth. Economic growth, unfortunately, has taken an incredible toll on Chile's natural environment. Air, water and soil pollution are common in both industrial areas and major cities. Due to the highly visible nature of Chile's air pollution problem and an abundance of land, solid waste pollution has not been at the forefront of the pollution control sector. As the new law and accompanying regulations develop, opportunities will emerge, mainly for incinerators, hazardous waste treatment, and waste separation and recycling systems.

Despite its present cold climate, the Arctic land masses once lay much farther to the south and were gradually carried northward by plate tectonic motions. For example, in the Late Carboniferous northern Greenland, which was part of Pangea, was situated at only 30 degrees N with the Panthalassa Sea to the north. By Late Jurassic-Early Cretaceous, a series of allochthonous blocks had collided with both the North American and Siberian plates. The Pacific Ocean was separated from the Arctic Basin by rotation of the North-Slope Chukotka block counterclockwise away from the Canadian Arctic Islands by Mid Cretaceous. It is speculated, based on the magnetic patterns, that the Alpha-Mendeleev Ridge complex may either have been a separate precursor block or may represent oceanic crust modified by a hot spot. Sea floor spreading in Late Cretaceous or Early Paleocene rifted the presentMakarovBasin in a wedge-shaped manner, with the Siberian end wider than the Canadian. The Eurasia Basin has a well-ordered set of magnetic anomalies, and thus this basin can be confidently dated to have been created just after the Cretaceous-Tertiary boundary. Creation of the Eurasia Basin eventually opened the pathway for exchange of waters between the Arctic and Atlantic oceans. The cold-oxygen rich waters from the Arctic ventilate the world's oceans and provide an important mechanism for global heat transfer and for the cycling of nutrients and carbon.

P. Lee Cruise L3-84-SP) AN - 52132651; 2002-024186 AB - Reconnaissance geophysical and geological surveying was conducted at Valu Fa Ridge, a back-arc spreading center in Lau Basin, to assess the potential for hydrothermal venting. A high-amplitude, phase-reversed reflection 1.5 s beneath the ridge axis was imaged on seven multichannel seismic reflection profiles. This reflection event is interpreted as the top of an axial magma chamber which may continuously underlie Valu Fa Ridge from at least 21 degrees 53'S, 176 degrees 30'W to 20 degrees 40'S. 176 degrees 45'W. Elevated concentrations of (super 3) He and particulate and dissolved Mn obtained at a single hydrocast station above the ridge crest suggest the regional presence of hydrothermal venting at Valu Fa Ridge. The sea floor is characterized by porous volcanic rubble which favors a diffuse, low temperature style of venting. Temperature anomalies in the near-bottom water detected during towed camera runs, and the recovery of hydrothermal smectite provide additional evidence for hydrothermal activity.

The hydrological and meteorological conditions that led to the flood were unique, complex, and extreme in many aspects. A brief description of the hydrometeorological setting that led to The Great Flood of 1993 is presented. Also presented is a summary of the human and economic impacts of the flood. In view of the magnitude of the losses, it is clear that every effort must be taken to reduce potential future losses. Many lessons already have been learned from The Great Flood of 1993. Foremost among these is the need to accelerate the implementation of an Advanced Hydrologic Prediction System. The major components of this advanced prediction system are presented and comparisons are made between forecast capabilities employed during The Great Flood of 1993 with those that will be possible once an Advanced Hydrologic Prediction System is in place. A significant functionality of the advanced prediction system must be more effective linkage of meteorological and climatological forecast and outlook information with the hydrologic forecast system. This is especially important for future precipitation. Inability to adequately incorporate precipitation forecasts was the single largest source of error for the longer-term hydrologic forecasts during The Great Flood of 1993. One approach for improving this deficiency as part of an Advanced Hydrologic Prediction System is described.

The proximity of significantly elevated isopycnals to the deep fluorescence maxima suggests that the out-cropping density surfaces represented paths along which particulate matter was transported. In one specific case, a relict-chimney (observed during a three-dimensional survey near the ice edge) appeared to have transported cooled, saline water of Atlantic origin and its associated biomass to mid-depths along inclined isopycnals. It is postulated that enhanced surface cooling necessary to establish deep isopycnal outcropping within the euphotic zone coupled with the high rate of particulate matter generation in the spring represents the primary mechanism by which the observed biogenic material was vertically transported to depth. The spatial and temporal scales over which biogenic transport occurs range from several km (chimneys) to hundreds of km (northern front of the Greenland Sea) and days to weeks.

Pre-shift and post-shift time differ in that precession-driven variations become more important in the late Quaternary; at the same time the 100 kyr cycle becomes dominant. A number of possible explanations have been put forward to explain the change in character of climatic fluctuations, calling on non-linear feedback mechanisms within a steady-state system, among which are ice-mass responses to extreme size increase (such as basal melting) and extension of lowland ice over shelves, where marine downdraw becomes possible. Here we emphasize the role of the unidirectional modifications of land morphology by ice erosion (as proposed by Nansen) as a factor in generating deep shelves (e.g., Barents Sea), valleys for channelling of ice, and uplift providing for mountain peaks where a new ice buildup can begin after an interglacial has run its course. Also, we consider that increased positive feedback from variations in albedo and atmospheric carbon dioxide is important, and we present evidence for a significant role of ocean circulation (Nordic heat pump) for the time after the Mid-Pleistocene Revolution.

To date, these comparisons have come mainly from ice-core data, which show a strong correlation between past atmospheric CO (sub 2) concentration and polar temperature. A new method is presented for reconstructing atmospheric CO (sub 2) concentration using the (super 1) 3C/ (super 1) 2C ratio (delta (super 1) 3C) in mosses and sedges in peat. The method exploits the fact that, unlike sedges and most other plants, mosses do not possess stomata, and are therefore unable to regulate their uptake of CO (sub 2) and water. The delta (super 1) 3C of mosses thus depends on both atmospheric CO (sub 2) concentration and available water, and the delta (super 1) 3C of sedges from the same peat can be used to remove the water signal. The method provides a resolution of about a decade--much higher than is possible from ice cores. Initial results for the past 14,000 years show three sharp increases in atmospheric CO (sub 2) concentration: at 12,800 years ago, corresponding to an episode of warming in the North Atlantic region; 10,000 years ago, corresponding to the end of the Younger Dryas cold period; and 4,400 years ago, after which time modern climates were established globally.

Organisms present at total suspended matter concentrations as low as 10mg/l released enough organic compounds during 1 day to negate the initial removal of the hydrophobic dissolved organic matter by Sep-Pak columns. In these experiments, the coating of particulate inorganic surfaces with organic matter may have also prevented Cu from establishing a chemical equilibrium between these particulate surfaces and the solution. The behavior of added radioactive Cu is consistent with an equilibrium model if the transfer of organic matter between dissolved and particulate phases by organisms is considered. In contrast, the behavior of natural Cu in these biotic suspension indicate that the partitioning of Cu was controlled as much by active biological processes as by chemical equilibria.

Estuarine particulate matter was suspended in two solutions: (1) filtered seawater, and (2) filtered seawater in which the hydrophobic organic matter had been removed. Radioactive Cu was then added to each suspension. The removal of hydrophobic dissolved organic matter resulted in a two-fold increase in the distribution coefficient (K (sub D) ) of added radioactive Cu (from 10 (super 4.50) to 10 (super 4.81) l/kg). The partitioning of (super 64) Cu in the suspensions was controlled by chemical processes dominated by complexation with particulate and dissolved organic matter.

The spreading corridor southwest of Fracture Zone XII is characterized by a rift valley and an usually small subsidence constant of 226 + or - 13 m/m.y.1/2, while the two spreading corridors immediately northeast of Fracture Zone XII have an axial high and a subsidence constant consistent with the global average. This abrupt variation in ridge morphology is not usually characteristic of medium-rate spreading centers, nor is such an abrupt variation expected of adjacent ridge segments that are spreading at the same rate. We suggest that a thermal anomaly beneath the ridge may influence the first-order effects of spreading rate and lithospheric cooling enough to produce the observed rift valley and axial high and the different subsidence constants. Although we are not certain what would produce the thermal anomaly here, we speculate that when the spreading rate on the Pacific-Antarctic ridge increased from slow to intermediate rates since 20 Ma, so did the need for materials for accretion, which may be supplied in part by along-axis asthenospheric flow from hotspots or a hot region to the northeast. A sufficient supply of hot asthenosphere may still be lacking in the ridge segment with the axial valley to the southwest, leaving it cooler and starved for accretionary materials.

Corrections for variations in atmospheric angular momentum (AAM) significantly reduce the scatter of the measured amplitudes across both time and frequency. The AAM corrections are found to reduce the scatter in the observed tidal amplitudes by as much as 60% for periods as short as 5.6 days; in contrast, earlier studies have shown a loss of coherence between AAM and length-of-day (LOD) for periods shorter than about 10 days. The tidal amplitude measurements place bounds on both the nonequilibrium ocean and mantle anelasticity effects. The in-phase k/C determination is found to agree to better than 0.5% with the value of 0.944 from Yoder et al. (1981). The out-of-phase values are found to have a frequency dependence that can only be explained by nonequilibrium ocean effects. The observed slope is larger than the theoretical by about 3 times the expected error. This result may indicate that the ocean is farther out of equilibrium for the higher frequencies than present models permit. Significant improvements are needed in both ocean and atmosphere modeling to exploit the full capability of the VLBI observations. Copyright 1994 by the American Geophysical Union.

A study was completed to determine if the JUP possibly could be used for conservation storage for any number of days from April 15 through May 14 under certain hydrologic conditions. The methods of the study were: (1) Frequency analysis of recorded daily mean discharge data for streamflow-gaging stations upstream and downstream from Pueblo Reservoir, and (2) Implementation of the extended streamflow prediction (ESP) procedure for the Arkansas River basin upstream from the reservoir. The frequency analyses enabled estimation of daily discharges at selected exceedance probabilities (EP's), including the 0.01 EP that was used in design of the flood- storage capacity of Pueblo Reservoir. The ESP procedure enabled probabilistic forecasts of inflow volume to the reservoir for April 15 through May 14. Daily discharges derived from the frequency analyses were routed through Pueblo Reservoir to estimate evacuation dates of the JUP for different reservoir inflow volumes; the estimates indicated a relation between the inflow volume and the JUP evacuation date. To apply the study results, only a ESP forecast of the April 15-May 14 reservoir inflow volume is needed. Study results indicate the JUP possibly could be used as late as May 5 depending on the forecast inflow volume. JF - Water-Resources Investigations - U. S.

The results are compared with CBL heights determined from radiosonde measurements. The profiler provides continuous CBL height measurements with very good time resolution (30 minutes or less), allowing for detailed understanding of the growth and fluctuations of the CBL. In addition, the profiler provides information about the degree of definition of the CBL top and the thickness of the entrainment zone. The measurements discussed were taken during the Rural Oxidants in the Southern Environment II (ROSE II) experiment.

The purpose of the calorimeter, design functions, and inherent limitations of a particular design are discussed. The interactions between the hood structure and the fire and its plume are analyzed in the context of avoiding: flame impingement on the hood; enhanced combustion of a test article, over and above that of a free-burn; loss of combustion product plume gases due to spill-over below the hood; and unacceptable dilution of plume gases in the measurement section of the exhaust duct. The concept of the ideally designed hood is introduced, where, throughout the course of the burn of a test article the hood is always immediately above the flame tip and the exhaust rate always exactly matches the hood-ceiling- elevation plume-flow rate. Methods to partially or completely achieve the ideal design are presented. These include the combined features of adjustable hood elevation and adjustable hood exhaust rate.

The early commercial sea turtle landings were sporadically collected and were published in a series of U.S. Government fisheries documents. Unfortunately, they have never been collated and summarized into a single data base or document. These are important base-line fisheries data on U.S. threatened and endangered species of sea turtles and provide considerable insight into the sociology and economics of the turtle fishery. Additionally, these data also provide basic biological information, such as species composition, seasonality, and sizes. These factors are necessary for understanding the ecology of these unique reptiles and enable resource managers to formulate sound management and conservation strategies, as mandated by the Endangered Species Act of 1973, and subsequent amendments. In this report, the author summarizes the commercial U.S. sea turtle landings as reported by he U.S. Fisheries Commission, Bureau of Commercial Fisheries and National Marine Fisheries Service for the continental U.S., Puerto Rico, and Hawaii.

The effect was calculated for a binary alloy. The dependence of the interface kinetic coefficient on crystallographic orientation is based on the motion and density of steps. Anisotropic kinetics give rise to travelling waves along the crystal-melt interface, and can lead to a significant enhancement of morphological stability. This self-stabilization arises because the travelling step density wave. The stability enhancement increases as the orientation approaches a singular orientation and as the solidication velocity increases. Specific calculations were carried out for Ge-Si alloys.

The sanctuary Management Plan identifies 4 goals: resource protection, research, interpretation, and visitor use. The sanctuary staff have identified 3 key uses of a geographic information system (GIS) that will help achieve these goals: site characterization, monitoring, and disaster preparation. A GIS--in this case, a marine GIS--is a tool that the sanctuary staff can utilize to map resources and analyze the effects of man or nature on the environment of the sanctuary.

For most estuarine-dependent fish populations, the earliest (age 0) life stages are most sensitive to changes in habitat quality. The difficulty for fishery managers lies in relating changes in age 0 survival rates to changes in abundance of older ages. Eggs-per-recruit (EPR), measured as the potential lifetime fecundity of an age 1 female, is used to compare the effects of changes in age 0 survival and fishing mortality rates on the reproductive potential of three fish species that are estuarine-dependent: winter flounder (Pleuronectes americanus), stripped bass (Morone saxatilis) and shortnose sturgeon (Acipenser brevirostrum). For striped bass and shortnose sturgeon, small changes in fishing mortality rates can have the same effect on reproductive potential as large changes in age 0 survival rates; whereas for winter flounder, changes in age 0 survival rates and fishing mortality rates of approximately the same magnitude have equivalent effects on reproductive potential. The difference in the relationships of age 0 survival and fishing mortality rates to reproductive potential between winter flounder and the other two species is because winter flounder have fewer age groups vulnerable to fishing mortality, an earlier age of full maturity, and higher total mortality rate than either striped bass or shortnose sturgeon.

This is somewhat less than the mass loss reported for territorial adult male pinnipeds. During fasting, absolute rates of mass change (averaging -0.68 kg/day) were positively correlated with initial mass. Mass-specific rate of change (averaging 2%/day) did not vary with age or initial mass. Although they lose large amounts of mass while fasting, immature male fur seals achieve a net increase in mass during the breeding season by making feeding trips to sea. We postulate that the capability for prolonged fasting in immature males facilitates the development of social and sexual skills that are likely to increase future reproductive success.

Some computer models for oil spill prediction can be useless in actual spill incidents because they cannot operate with the limited amount of input data available in an emergency or because their output cannot directly answer questions posed by spill response personnel. Moreover, weathering models typically idealize a spill incident to such an extent that the results of a simulation may bear little resemblance to what happens in a real spill. We conclude that the key features of any oil-weathering model are: flexibility in the input requirements, ease-of-use, computational speed, uncertainty estimates of the model predictions, and output display based on possible spill response decisions. We discuss the design criteria used in the construction of ADIOS, incorporating the above factors, as well as computational constraints due to choice of platforms on the numerical solutions of the weathering algorithms. Model results for a recent spill are reviewed. JF - SOCIETY FOR COMPUTER SIMULATION, P.P. BOX 17900, SAN DIEGO, CA 92177 (USA). pp. 56-60. 1994.

This probability can be calculated under the assumption that the initial velocity and launching angle of a fragment are uniformly distributed random variables. Since air drag cannot be neglected in most practical cases, equations of motion must be solved numerically to compute this probability. This paper presents an implementation of a procedure for calculating this probability. JF - SOCIETY FOR COMPUTER SIMULATION, P.P. BOX 17900, SAN DIEGO, CA 92177 (USA). pp. 84-90. 1994.

Part of that testing included participation in HYGRO'93 where field testing of the SeaBat-9001 was conducted in the Bay of Fundy, New Brunswick, Canada, on board the R/V Mary-O and the CHS Vessel Frederick G. Creed. Based on HYGRO'93 data, the SeaBat-9001 was determined to have a slant range precision of 2.55 centimeters. Comparison between SeaBat-9001 data collections from the Mary-O and the Creed showed excellent agreement with less than 100cm super(2) variance between surveys conducted of the same area on different days. It is concluded that the SeaBat-9001, when appropriately integrated into a survey system, can satisfy the applicable shallow water standards of the International Hydrographic Organization.

In each year, divers collected all mussels within a 0.5 m super(-2) frame, with 10 replicate quadrats being sampled at each station. In the southeastern portion of the lake where mussels have been established since 1988, densities in 1992 were similar or lower than densities found in 1990. On the other hand, although still lower than densities in the southeastern portion of the lake, densities in the northwestern portion of the lake increased between 1990 and 1992. The size structure of mussel populations in the two regions were quite different. For similar substrate types (unionids), mussels less than 5 mm in shell length comprised 53% of the population in the southeastern portion of the lake compared to only 20% in the northwestern portion. The latter region has colder temperatures and lower food supplies than the former region. Over the entire lake, the maximum density at an individual station was 11,000 m super(-2) in 1990 and 25,000 m super(-2) in 1992. JF - IAGLR, BUFFALO, NY (USA). 166 p. 1994.

This is especially important because epizootiologic studies have shown a positive association between environmental carcinogens, such as polycyclic aromatic hydrocarbons, and increased prevalence of neoplasms and related lesions, primarily in liver, of benthic fish species (Microgadus tomcod) (Pseudopleuronectes americanus) from a wide range of urban and industrialized areas. In studies with wild fish and mammalian species the super(32)P-postlabeling assay, as developed for aromatic compounds, has been used most extensively because of its high sensitivity and ability to detect structurally uncharacterized adducts. The results to date of field and laboratory studies show that hepatic DNA adducts detected in fish are associated with increased exposure to environmental polycyclic aromatic compounds in the preponderance of species examined, whereas in the limited studies with wild mammals, such a relationship is equivocal at present. The findings with fish suggest that DNA adducts, as measured by super(32)P-postlabeling, have the potential to be effective molecular dosimeters of exposure to environmental carcinogenic aromatic compounds and thereby may lead to an improved understanding of the etiology of neoplasia in wild teleosts.

Accurate determination of the cyclone center position, based on Doppler velocity measurements, will become essential for the issuance of hurricane advisories, forecasts, and warnings once a network of WSR-88D Doppler radars is deployed on the United States coastlines, islands, and military bases during the 1990s. This will allow high-resolution detection and tracking of hurricanes nearing land for the first time. Simulated Doppler velocity data, which were reconstructed from wind field data collected by reconnaissance aircraft during Hurricanes Alicia (1983) and Gloria (1985), were used to test the concept of using ground-based Doppler radar data to estimate cyclone center location. The center range and azimuth estimates of a hurricane signature were calculated from the simulated coastal Doppler radar velocity data. Preliminary results indicate that the technique performed well for estimating center locations from the radar measurements compared with storm center positions determined from in situ aircraft measurements.

B-cell mediated immunity was assessed by examination of the primary and secondary plaque-forming cell (PFC) responses of anterior kidney and splenic leukocytes to a T-independent antigen, trinitrophenyl-lipopolysaccharide (TNP-LPS) and to a T-dependent antigen, TNP-keyhole limpet hemocyanin (TNP-KLH). Salmon exposed to DMBA at dosages of 20% or 1% of the 96 hr LD sub(50) (12.7 mg and 0.6 mg/kg of salmon, respectively) or to PCBs at a dosage of 20% of the 96 hr LD sub(50) (54.0 mg/kg of salmon) exhibited a suppressed PFC response. The secondary PFC response of anterior kidney and splenic leukocytes to both antigens and the primary splenic PFC response to TNP-LPS were suppressed in salmon exposed to either DMBA or PCBs. However, only the primary PFC response of anterior kidney leukocytes to TNP-LPS was suppressed in salmon exposed to PCBs and no suppression of this response was observed in salmon exposed to DMBA. Neither anterior kidney or splenic leukocytes from salmon exposed to DMBA or PCBs showed an altered primary PFC response to the T-dependent antigen, TNP-KLH. These results suggest that B-cell mediated immunity in salmon is suppressed by known mammalian immunosuppressants and that suppression of the PFC response observed previously in salmon from an urban estuary may be due to contaminant exposure.

Isochrysis isolates are from several geographic locations, and their relationships to each other are not known. Research reports of Isochrysis growth characteristics, biochemical composition, and nutritional value to invertebrates suggest that a number of these strains differ in terms of their taxonomy and fundamental biology; their practical use as mariculture feeds differs as well. In this note, we discuss origins of some of these strains, describe differences between these from our own and others' research, and recommend that researchers be cognizant of the cultural history of their Isochrysis strains because differences between them will affect their use as mariculture feeds.

Nehlsen et al. (1991) identified over 200 stocks they considered to be at some risk of extinction and over 100 already believed to be extinct. Major federal stock restoration programs are under way in the Columbia and Klamath River basins, and several populations of Pacific salmon have recently been listed as threatened or endangered under the U.S. Endangered Species Act. Although there is widespread agreement that recovery programs are needed for Pacific salmon, there is less agreement over what constitutes recovery.

As part of this project, zebra mussels (Driessena polymorpha) have been collected at 13 sites along the shores of the Great Lakes from Green Bay through Lake Huron to the western end of Lake Erie. Three samples of approximately 250 large specimens each were obtained from each site, and each was analyzed for concentrations of 70 contaminants including 12 trace metals and 4 major elements. The levels of a number of the metals, generally those most used in industrial processes, were clearly different among the various sites. Higher concentrations of these metals were found downstream from the major industrialized areas with concentrations of 4 to 7 times at the most contaminated sites compared to the sites further removed from anthropogenic sources.

AN - 16979167; 3627691 AB - There is considerable evidence that different classes of chemical contaminants which accumulate in subtidal sediments are responsible for a variety of serious biological effects in marine organisms exposed to such compounds. While much of this information is derived from laboratory studies, there is an increasing body of data from field studies which supports such relationships between contaminants in subtidal sediments and biological damage. Accordingly, there is a desire to reduce the exposure of marine organisms to chemically contaminated sediments, and various methods for doing this have been proposed. The most common approaches rely on either removal of sediments by dredging, or some type of physical sequestration of sediments, generally through the placement of a cap over contaminated areas. A question which has not been adequately addressed is whether or not such treatments will result in a lessening of the risk to living marine resources. A major focus of this presentation will be a discussion of the development and appropriate use of technologies for assessing the efficacy of subtidal sediment remediation. Areas to be discussed in detail include the use of screening technologies for rapidly assessing contamination of sediment and biota, and the use of biomarkers to expedite the determination of biological injury to marine species. Examples will be given of the use of these techniques in Puget Sound, Washington, USA, where several subtidal sites have undergone or will be undergoing remediation.

Modifications to the model permitted radiative effects of the smoke plume to modify the pollutant's vertical mixing. Calculated SO sub(2) (sulfur dioxide) air concentrations were compared with the observations from several intensive aircraft measurement compaigns as well as longer-term ground-based measurements. Model sensitivity tests and comparison to the aircraft measurements confirmed (1) the magnitude of the tabulated emission rates for SO sub(2) and carbon soot; (2) the most appropriate value for the smoke's specific extinction coefficient was about 4 m super(2) g super(-1); (3) that the model was sensitive to the vertical mixing in the first 100 km downwind from the fires; (4) that the SO sub(2) conversion rate was about 6% h super(-1); and (5) although there were large variations in the height of the initial smoke plume and ground-level concentrations were most sensitive to that height, an average value of 1500 m a.g.l. (above ground level) provided reasonable model predictions. Six ground-level sampling locations, all along the Arabian Gulf Coast, were used for model evaluation.

A technique was developed to analyze NOAA polar orbiting satellite imagery to obtain horizontal smoke plume positions. The plume heights were obtained by combining the satellite analysis with back trajectory results. Backward trajectories were computed using both coarse and fine resolution MRF wind fields. The average of the absolute value of relative trajectory error (vertical bar R.T.E. vertical bar) for the late summer period (24 July-15 September 1991) was about 10% of the travel distance when using the fine grid trajectories with the optimum plume centroid height and 14% when using the coarse grid model output. The absolute R.T.E. for the optimum plume height runs was half of the R.T.E. for the constant starting height run (vertical bar R.T.E. vertical bar = 0.21). This difference indicates the importance of proper specification of plume centroid height when using high resolution meteorological data for transport studies. Use of the standard coarse grid MRF wind fields to drive the transport model was shown to lead to large errors near the source due to the poor horizontal and vertical resolution.

Laboratory and field studies show tunas are not strictly prisoners of their own thermoconserving mechanisms, but have rapid and extensive control over the efficacy of their vascular countercurrent heat exchangers. Skipjack tuna (Katsuwonus pelamis) are, therefore, probably not forced out of formerly suitable habitats as they grow because of the potential for overheating, as formerly thought. Because of their thermoregulatory abilities, bigeye tuna (Thunnus obesus) apparently can exploit food resources well below the thermocline by minimizing rates of heat loss when in cold water, and then maximizing rates of heat gain from the environment during brief upward excursions into the warmer mixed layer. Widely cited estimates of limiting oxygen levels, based on estimated metabolic rates at minimum hydrostatic equilibrium swimming speeds, are not accurate because tunas have exceptionally high oxygen demands even at slow speeds. High metabolic rates, even at slow swimming speeds, most likely result from the high osmoregulatory costs engendered by tunas' large thin gills and/or their other adaptations for achieving exceptionally high maximum metabolic rates. Recent laboratory research and modelling efforts suggest the capacity of tunas' cardiorespiratory systems to deliver oxygen at extraordinarily high rates was evolved to allow rapid recovery from strenuous exercise, rapid digestion, and high rates of gonadal and somatic growth, not high sustained cruising speeds. The rate at which reduced ambient oxygen levels prolong the time required for tunas to recover from strenuous exercise appears to be a good index of habitat suitability, with respect to oxygen.

In each of 3 years, photoperiod treatment began in late December or January and continued for 13 to 18 weeks until release between 29 March and 5 April into the Clearwater River. Additional groups exposed to either the advanced photoperiod or ambient light were reared at an elevated water temperature (11-12 degree C) for 10 to 14 days preceding release. Downstream movement and recovery proportions were evaluated using passive-integrated-transponder (PIT) tags. Photoperiod treatment increased gill Na super(+)-K super(+) ATPase levels significantly at the time of release in 2 of the 3 study years and in all 3 years resulted in significantly faster travel times to Lower Granite Dam, 117 km downstream. The combination of photoperiod and increased temperature treatment resulted in the highest gill Na super(+)-K super(+) ATPase levels at release, the fastest downstream movement, and significantly higher recovery proportions downstream. Temperature treatment alone had no effect on gill Na super(+)-K super(+) ATPase level or recovery proportion and resulted in significantly slower travel time to Lower Granite Dam. Treatment groups exhibiting faster travel time to Lower Granite Dam also passed McNary Dam (343 km downstream) sooner, although the differences were not as great.

Corresponding to this increase, researchers and fishermen have observed an increase in the incidental capture of harbor seals in GOM sink gillnet fisheries. At the same time the perception among some fishermen is that harbor seal predation on commercially important groundfish is significant. During this period groundfish abundance has steadily declined, principally due to overfishing. This has increased concerns in the fishing community that the growing seal population may impede fish stock rebuilding efforts. However, current knowledge of harbor seal diets are insufficient to draw firm conclusions regarding seal predation on commercially valuable groundfish.

Methods to combine radiometric and ceilometer measurements were developed to improve both the retrieval accuracies of integrated water vapor and liquid water. The rms difference between the retrieved and radiosonde-measured integrated water vapor was 6% relative to the mean. Compared to radiosondes the temperature profiles retrieved using a linear statistical inversion technique were accurate to 1.28 degree C. However, since the radiometric temperature profiles were no more accurate than profiles obtained from climatology, the surface-based radiometer provided essentially no new information regarding the environmental temperature profiles.

Measurements at offshore locations in water depths greater than 100 m have disclosed current speeds exceeding 25 cm/s at 1 m above the lake floor during winter storms when the lake water is unstratified. Counterclockwise veering of the current velocity vector occurs as the bottom is approached, with the veering being most rapid close to the bottom. Measurements of currents during winter and spring have shown prevailing cyclonic circulation at all water depths. This is true of the other deep Great Lakes as well. Mass conservation calculations with the current meter data yield upwelling velocities on the order of 1 m/day in the center of the lake during winter. Water temperature data have been obtained from thermistor strings attached to meteorological buoys moored in the center of the lake by the National Data Buoy Center, Bay St. Louis, Mississippi. Simulations of the temperature data with four different one-dimensional mixed layer models were all premature in timing the onset of stratification. Additional simulations of the temperature data were made with a constant upwelling velocity imposed through late spring. Results of the new simulations were significantly improved over those neglecting upwelling. These results emphasize the importance of Ekman pumping in retarding the start of stratification in large lake basins.

These sites, generally removed from the effects of local pollution sources, show characteristics that typify broad geographical regions. At Barrow, AK; Mauna Loa, HI; American Samoa; and South Pole, data records of 15-20 years show trends that in all cases are a function of season. This dependence on season is important in understanding the causes of the long-term changes. At Barrow, the summer (July, August, September) increase of 1.7% per year is probably indicative of photochemical production. At South Pole, on the other hand, the summer (December, January, February) decrease is related to photochemical losses and enhanced transport from the coast of Antarctica. At all the sites there is a pronounced seasonal variation. In the Southern Hemisphere (SH), all locations which run from 14 to 90 degree S show a winter (July-August) maximum and summer minimum. In the Northern Hemisphere (NH) most of the sites show a spring maximum and autumn minimum. At Barrow (70 degree N) and Barbados (14 degree ), however, the maxima occur during the winter, but for very different reasons. At many of the sites, the transport changes associated with synoptic scale weather patterns dominate the day-to-day variability. This is particularly pronounced at Bermuda and the more tropical sites. JF - Atmospheric Environment AU - Oltmans, S J AU - Levy, H II AD - Clim. Monit. and Diagn.

Our success in finding eddies resulted from placing buoys in high concentrations of walleye pollock (Theragra chalcogramma) larvae. We utilize data from hydrographic surveys, satellite-tracked buoys and moored current meters to describe the eddies. Small (< 25 km diameter) eddies likely transit along the slope of the eastern Bering Sea every 45-60 days. In previous studies such small features were not observed because their size fell within typical separation of hydrographic stations and the weak sea surface temperature gradients are not resolved by satellite-borne infrared imagery.

Historical Lake Ontario outflows could not be used for the study because of anthropogenic effects reflected in the data, the statistically short record length, and autocorrelation of the data. Stochastically generated Great Lakes net basin supplies were used in a Great Lakes hydrologic response model to obtain Lake Ontario levels and outflows. A significant problem was the lack of robustness in the Lake Superior and Lake Ontario regulation plans during simulations with extreme water supplies. The regulation plans were modified consistent with the International Joint Commission's regulation criteria and past operational actions to give reasonable results under these conditions. The simulated Lake Ontario levels and flows had a greater range than those resulting from historical water supplies. The maximum simulated Lake Ontario quarter-monthly level was 76.41 m (IGLD 55), and the maximum simulated quarter-monthly outflow was 14,160 m super(3)/s. The maximum-flow limitation of Lake Ontario's regulation plan, 8,780 m super(3)/s, was exceeded 0.27% of the time. The upper lake-level regulation limit, 75.22 m, was exceeded 0.15% of the time. It was found that some of the regulation criteria cannot be met simultaneously under extreme conditions. Historical water supplies, the current standard for the design and evaluation of modifications to the operational regulation plans, should no longer be the sole test of the plans.

Most eggs were found below 150 m to near bottom ( similar to 300 m) but progressively shallower later in the season. Eggs in middle stages of development were found at shallower depths than were younger or older eggs. The vertical distribution of eggs was positively related to observed differences in seawater temperature but showed no relationship to density. Larvae hatch at incubation depth and quickly rise to the upper 50 m of the water column where they remain during larval development. Larger larvae ( similar to 7-10 mm standard length [SL]) undergo limited diel vertical migration within the upper 50 m. They are deepest during the day, shallowest at dusk, slightly deeper at night, and even deeper at dawn. Their mean depths of occurrence were between 21 and 37 m at all times. At these depths, prey (copepod nauplii) generally were at densities sufficient for larval pollock growth as determined in laboratory studies. Pronounced thermoclines and pycnoclines were present in the part of the water column inhabited by the larvae in late May. Larvae appear to remain below the upper mixed layer during periods of increased turbulence, but at depths during daytime where light was sufficient for feeding and where prey densities were adequate.

This paper establishes a spatial framework for the analysis of water quality behavior in the Florida Keys National Marine Sanctuary. It defines subareas as based upon the variability of circulation behavior and its affect on water quality. The spatial domains are suggested for the aggregation and analysis of data as affected by the circulation characteristics of the subarea for both strategic and tactical issues. The framework recognizes nine unique circulation regimes as based upon our current understanding of the circulation dynamics within the sanctuary and its surrounding waters. Application of the framework is viewed as part of an interative process as ongoing research and monitoring provide the basis for its refinement and use in the development of area specific water quality management strategies.

As in most other vertebrates, this type of high intensity activity in fish is fueled anaerobically. In the early stages of activity energy (as ATP) is derived from the breakdown of high energy phosphates stores, which in vertebrates is phosphocreatine (PCr). Once PCr stores are depleted (within 15 seconds), ATP is derived from the anaerobic breakdown of glycogen. Associated with the breakdown of muscle glycogen and hydrolysis of ATP is an accumulation of lactate and H super(+); the latter resulting in a reduction in intracellular pH (pHi) by as much as 0.4 pH units. Fatigue appears to set in once energy reserves have been depleted, as in exhausted fish, muscle levels of glycogen, ATP and PCr are often below the limits of detection. In the more active fish species, such as salmonids, some of the lactate and H super(+) produced leaks out of the muscle into the blood space, resulting in blood lactate levels of 15-20 mM and a depression in blood pH by about 0.5 units. The peak blood acidosis occurs immediately after cessation of swimming, while blood lactate levels do not peak until 2-4 hours after exercise. Associated with the metabolic and acid-base disturbances are increases in the circulating levels of the "stress" hormones: epinephrine, norepinephrine and cortisol.

The protein fraction of the diet is responsible for more than 60% of the cost of the diet. Research has, I feel, been misdirected towards reducing feed costs ($/kg feed) through the substitution of less expensive animal and plant proteins for fish meal. Relatively little attention appears to have been paid to improving feed efficiency (kg feed/kg fish produced) which also affects production costs: $/kg feed x kg feed/kg fish produced = $/kg fish produced Inefficient diets lead to additional feed handling, do not allow fish to grow to their potential and contribute to pollution. Factors that contribute to poor feed efficiency are: feed loss, poor digestibility, improper protein/energy ratio, poor amino acid balance and high levels of carbohydrate, fiber and ash.

Forecast variables include the surface water level fluctuation, horizontal and vertical structure of temperature and currents, and turbulence. The system uses meteorological observations, satellite data, and forecasts from numerical weather prediction models as input. Lake circulation and thermal structure are calculated using a three-dimensional hydrodynamic prediction model. Output from the model is used to provide information on the current state of the lake and to predict changes for the next two days. This information is used by scientists, government agencies, commercial operations, and the public for enhancement of commercial and recreational activity, resource management, and hazard avoidance. This paper describes system design, data acquisition and analysis procedures, the hydrodynamic model, and sample model output. The initial implementation of the system provides daily nowcasts of system variables for one lake, Lake Erie. Requirements for implementing actual lake forecasts are discussed.

Altogether, 1,060 fish captured by commercial groundfish and shrimp trawlers between July 1986 and July 1987 were examined. Reproductive events were protracted. Insemination of females occurred from August to December, and fertilization and parturition followed from December through March. Spermatozoa were observed within both vitellogenic and previtellogenic ovaries between July and November. Reproductive events in smaller males and females were delayed relative to those in larger individuals. Females attained 50% maturity at a greater size (36.5 cm total length) and age (8.4 years) than males (29.6 cm total length; 5.1 years). The unimodal development of eggs and larvae indicated one parturition per year. Most age-6, age-7, and age-8 females possessed ovaries in an intermediate "maturing" condition. Histological analysis revealed that most of these females were immature; ovaries showed no evidence of previous spawning, oocytes never developed beyond an early vitellogenic stage, and during months of parturition, many of these females were resorbing their advancing oocytes. Total fecundities ranged from 19,815 to 489,064 oocytes per ovary pair and increased exponentially with increasing fish length, linearly with fish weight, and asymptotically with fish age (6 to 66 years).

Photochemical oxidants in the northeastern United States were simulated for the period 2-17 July 1988, one of the most severe air stagnation episodes in the last decade. In the simulations, biogenic hydrocarbon emissions were adjusted by a factor of 3 to account for the existing range of uncertainty in these emissions. The impact of biogenic emission uncertainties on O sub(3) predictions depended upon the availability of NO sub(x). In most cases, O sub(3) concentrations increased in response to increases in biogenic hydrocarbon emissions. However, in some extremely NO sub(x)-limited areas, increasing the amount of biogenic emissions decreased O sub(3) concentrations. Two control strategies were also examined in the simulations: (1) reduced anthropogenic hydrocarbon emissions, and (2) reduced anthropogenic hydrocarbon and NO sub(x) emissions.

Benthic macrofauna and winter flounder were collected monthly and bimonthly, respectively, from July 1986 through September 1989 at three sites in the Bight apex that are variably influenced by sewage sludge. There were limited changes in winter flounder diets and abundance of dominant benthic macrofaunal species following cessation of sewage sludge disposal. The comparison of volumetric contribution of common prey in flounder stomachs to potential-prey abundance in benthic samples suggested several relationships. These included evidence of preferential predation on the polychaete Pherusa affinis; this selective preference may be associated with its high caloric content as well as with its average high biomass density. Other common prey, primarily polychaetes but including an anthozoan, were also preyed upon in proportions greater than their abundance in the environment. Some moderately abundant potential prey, such as the small near-surface-dwelling mollusc. Nucula proxima and the ribbon worm Cerebratulus lacteus were not commonly preyed upon suggesting they were unavailable as prey or were avoided by winter flounder. Corresponding fluctuations in abundances and predation of the pollution-tolerant polychaete Capitella sp. and the pollution-sensitive amphipod Unciola irrorata suggested a proportional consumption relationship in association with sludge disposal and its cessation.

Catch data from six multispecies ground-fish assessment surveys conducted at three-year intervals (1977-92) by the National Marine Fisheries Service's Alaska Fisheries Science Center revealed three assemblages. The first, a deep-water assemblage, consisted of shortspine thornyhead, Sebastolobus alascanus, Pacific ocean perch, Sebastes alutus, darkblotched rockfish, S. crameri, and splitnose rockfish, S. diploproa. Redbanded rockfish, S. babcocki, and rougheye rockfish, S. aleutianus, were closely associated with this group. The second assemblage consisted of canary rockfish, S. pinniger, yellowtail rockfish, S. flavidus, and green-striped rockfish, S. elongatus. This group was most abundant in areas over the middle shelf. The third assemblage, closely associated with the second, consisted of sharpchin, S. zacentrus, rosethorn, S. helvomaculatus, and redstripe, S. proriger, rockfish. While the three assemblages may be of particular interest to ecologists, managers faced with the division of the Sebastes complex management unit into groups that better reflect rockfish cooccurrence may only be able to manage the latter two assemblages as one shelf-rockfish unit.

In separate aquaria, 81 pairs of juveniles covering a wide range of size differences (total lengths differing by 12 to 61 mm) were held and monitored over a 4 day period. Complete consumption, in which a smaller fish was swallowed whole by a larger fish, occurred 11% of the time. In 36% of the pairs, attacks by the larger fish resulted in mortality of the smaller fish. The mouth width:body depth ratio between the larger and smaller fish of a pair differed significantly depending on whether the smaller fish survived, was killed but not consumed, or was ingested whole by the larger fish. Cannibalistic individuals could consume fish close to the maximum size physically possible under gape limitation; at this size the length of the cannibal was approximately 1.7 times the length of the prey. Length-frequency distributions of age-0 pollock in field concentrations suggested that, at least in some geographical areas, potential cannibals and prey commonly co-occur. Unsuccessful predatory attacks by larger individuals may have additional detrimental effects on smaller pollock in natural populations.

The procedure uses a numerical model called Target Transformation Factor Analysis (TTFA) to estimate source emission profiles using ambient trace element air concentration data. The profiles estimated by TTFA are then employed in a Chemical Mass Balance (CMB) source apportionment analysis for an air shed. Other known sources are estimated using source signatures from the literature. The results show that TTFA can be used to provide quantitative estimates of air pollution source profiles for an urban center in China. The number of profiles for unique source types was limited for this data set since emissions from certain types of sources co-varied during each sampling day. Consequently, the CMB analyses that applied the TTFA source profiles needed to be supplemented with standard U.S. EPA source profiles. TTFA can identify source categories of airborne pollution for specific locations, as well as give quantitative data on the composition of the emissions from those source types. The source profiles obtained through a TTFA can be used in a chemical mass balance source apportionment calculation.

Free embryos exhibited positive geotaxis 1 d post hatching, actively swimming through a density gradient to remain in the lower water column. Activity increased with free embryo development and by 7 d post hatching, feeding-ready larvae reversed their vertical orientation, now exhibiting negative geotaxis as they migrated to the upper water column. The results indicate that even at the earliest developmental stages, walleye pollock possess the capability to control vertical distribution. Laboratory results are compared with patterns of vertical distribution observed in the sea. JF - Environmental Biology of Fishes AU - Davis, M W AU - Olla, B L AD - Coop. Inst. Mar. Resour.

A total of 1133 stomachs collected during June-July 1985, January 1988, and July 1988 were examined for contents; only 19.7% contained food items. The diet consisted of pelagic tunicates and other micronektonic animals that are associated with the vertically migrating sonic scattering layer that is advected over the seamount from the adjacent oceanic environment. Peak feeding occurred in the early morning on migrating organisms likely trapped by the expanse of the seamount summit during the morning descent. Newly recruited armorhead had lower feeding rates than older, previously recruited fish. Estimates of daily ration for previously recruited armorhead were 1.17 g (0.26% of body weight) in the summer of 1985 and 12.87 g (2.86% of body weight) in the summer of 1988. Since estimated values for the evacuation coefficient and the duration of the daily feeding period did not differ between sampling periods, the increase in daily ration was due to an increase in feeding rate. The proportion of the diet composed of pelagic tunicates was also higher in 1988. JF - Environmental Biology of Fishes AU - Seki, M P AU - Somerton, DA AD - Honolulu Lab., Southwest Fish. Sci.

The method is based on the size dependence of the movement of the particles in response to an acoustic wave transmitted into the cloud. The density change of the particles induced by this motion is detected with the delta-k lidar technique. A simple, one parameter cloud particle model is used to estimate the performance of the method at ranges from 3 m to 10 km. These performance estimates indicate that the technique may practical for both remote and in-situ sensing of cloud particle size parameters. JF - Atmospheric Research [ATMOS. RES.].

However, hatchery-reared fish may be less equipped behaviourally than wild fish to survive the challenges of the natural environment. One of the major causes of mortality in hatchery-reared Pacific salmon smolts is predation soon after release into the natural environment. Laboratory results on coho, Oncorhynchus kisutch (Walbaum) smolts demonstrated that the potential exists for mitigating deficits in antipredator behaviour. Stress associated with rearing practices, transport and release may render smolts more vulnerable to predation. Behavioural assays were developed to assess predator avoidance capabilities of stressed coho and spring chinook, O. tshawytscha (Walbaum) smolts. Social behaviour and capabilities of hatchery-reared salmon smolts to feed and grow in the wild may suffer from deficits caused by the hatchery environment. Based on laboratory studies, food availability and its influence on the development of behaviours such as aggression and schooling in chum salmon, O. keta (Walbaum) and schooling in walleye pollock, Theragra chalcogramma (Pallas) could potentially mitigate these behavioural deficits. The results of these studies demonstrate that ecologically meaningful quality assurance can be built into population enhancement efforts. JF - Aquaculture Research [AQUACULT. FISH. MANAGE.]. 1994.

With an increase of the globally constant storage capacity, evaporation from the continents rises and runoff falls, because a high storage capacity enhances the ability of the soil to store water from periods of excess for later evaporation during periods of shortage. In addition to this direct effect, atmospheric feedbacks associated with the resulting higher precipitation and lower potential evaporation drive further changes in evaporation and runoff. Most of the changes in evaporation and runoff occur in the tropics and in the northern middle-latitude rain belts. Global evaporation from land increases by about 7 cm for each doubling of storage capacity in the range from less than 1 cm to almost 60 cm. Sensitivity is negligible for capacity above 60 cm. In the tropics and in the extratropics, the increased continental evaporation is split, in approximately equal parts, between increased continental precipitation and decreased convergence of atmospheric water vapor from ocean to land. In the tropics, this partitioning is strongly affected by induced circulation changes, which are themselves forced by changes in latent heating. The increased availability of water at the continental surfaces leads to an intensification of the Hadley circulation and a weakening of the monsoonal circulations. In the northern middle and high latitudes, the increased continental evaporation moistens the atmosphere. This change in humidity of the atmosphere is greater above the continents than above the oceans, and the resulting reduction in the sea-land humidity gradient causes a decreased onshore transport of water vapor by transient eddies. Results established here may have implications for certain problems in global hydrology and climate dynamics, including the effects of water resource development on global precipitation, climatic control of plant rooting characteristics, climatic effects of tropical deforestation, and climate-model errors induced by errors in land-surface hydrologic parameterizations.

AN - 16907979; 3598829 AB - As of this writing, of 1,321 taxa listed on the U.S. federal listing of threatened or endangered organisms, only six have marine or estuarine phases in their life history. None of the six are wholly oceanic. Indecision as to the applicability of the Endangered Species Act (ESA) to wholly oceanic species stems from at least two sources: (1) lack of consensus on population criteria designating special status, and (2) societal and scientific doubt as to whether wholly oceanic species can become endangered. A cursory examination of marine fishes of U.S. territorial waters by regional specialists suggests that at least 39 species are severely depleted and deserve closer examination of their population status to determine eligibility for protection under the ESA. Several regional groupings of the candidate species suggest ecosystem-wide impacts. Where fishing is suspected to be causing large-scale disruptions of fish abundance and fish community relationships, establishment of marine reserves might be a prudent management policy.

Larvae were most abundant at intermediate salinities (i.e. frontal waters) where chlorophyll a and macrozooplankton displacement values were also highest. Using sagittal otolith microstructure, we estimated larval ages ranging from 3-14 d. These ages were used to back calculate spawning dates from 13-24 July and 22-31 August. Mean absolute individual growth rate (length age super(-1)) was 0.47 mm d super(-1), with the least squares linear regression SL = 1.67 + 0.47 AGE (r super(2) = 0.60, Pr > F = 0.0001) representing the best growth curve. Highest growth occurred at intermediate salinities near 31ppt., and temperatures near 29 degree C. There was significant temporal variation in growth, with larvae collected in July growing slower than those from September (0.37 and 0.48 mm d super(-1), respectively). The pooled instantaneous daily mortality rate (Z) of the larvae was estimated to be 0.33 d super(-1) (0.16 d super(-1) in July and 0.41 d super(-1) in September). These results show that significant spawning of yellowfin tuna may occur in the northern Gulf of Mexico in the vicinity of the Mississippi River discharge plume, and suggest that larval growth and survival may be enhanced in the plume frontal waters.

We evaluated the other otoliths, the lapilli and asterisci, as well as the sagittae, as ageing structures and length-at-age estimators in hatchery-reared and wild juveniles (< 50 mm SL). Our otolith mounting and sectioning protocol for preparing sagittal sections required significantly less processing time with no loss in accuracy than the more traditional transverse sectioning reported in the literature. Increments in asterisci were clearly visible from the primordium to the otolith margin, whereas the nuclear region of sagittae and lapilli were more opaque and prevented detection of all rings. Asterisci were not present at hatching, but on average from six days later, therefore the addition of a constant (6 days) to the ring counts of asterisci resulted in this otolith providing more accurate ages then sagittae or lapilli. According to coefficients of determination (r super(2)) generated from the relation between fish length and otolith diameter, the sagitta, asteriscus, and lapillus predict fish length in descending order. However, because inner rings on sagittae were usually undetectable, lengths at ages cannot accurately be predicted. All rings are observable in the asteriscus; thus, by using the 6-day adjustment factor accurate length-at-age prediction is possible.

To determine the potential change in exposure brought about by adding uncontaminated food, whole sediment contaminant bioaccumulation by the midge, Chironomus riparius, was determined in the presence and absence of added food. Lake Michigan sediment was dosed with radiolabeled polycyclic aromatic hydrocarbons (PAHs) and/or DDT and trans-chlordane. Three groups of organisms (Feeding Levels I and II plus a control) were exposed in static assays. After two-, four-, seven-, and ten-day exposures, individual larvae were analyzed for contaminant concentration, mass, and total lipid content. After 7 to 10 days, accumulation of pyrene and benzo(a)pyrene was significantly greater with feeding, while larvae exposed to chrysene accumulated significantly less contaminant when fed, compared to controls. No feeding-related differences in accumulation of the two insecticides were observed. Significant differences in larval mass between test animals and controls were observed only with pyrene-dosed sediment. Larval lipid content tended to remain constant throughout the exposures and did not differ between fed and unfed organisms. Thus, it appears that contaminant bioavailability can be altered by the addition of uncontaminated food. However, this phenomenon appears to be compound-specific and not broadly predictable.

Some early results AN - 16900009; 3805603 AB - An experimental coupled ocean-atmosphere model forecast system has been implemented at the National Meteorological Center (NMC) for routine multi-season climate forecasts. The ocean initial conditions for the forecasts are provided by an ocean data assimilation system which uses a basin model of the Pacific Ocean integrated with a four-dimensional variational data assimilation system. Pacific basin ocean reanalyses for the period 1982-1992 provided both the initial conditions and the verification fields for the coupled model forecasts. The coupled model consists of a modified T40 version of NMC's operational medium range forecast model coupled to a Pacific basin ocean general circulation model. Hindcast experiments starting on the first of every month from October 1983 to 1993 have been made to establish the skill of this system in forecasting sea surface temperature variability in the tropical Pacific with lead times of up to several seasons. The system consistently out performs persistence forecasts even at short forecast lead times, and is able to forecast most of the sea surface temperature variability that occurred in the tropical Pacific during 1984 to 1993.

The conventional explanation for this less-than-linear growth is that the diffusion is undergoing a transition from the near-field to the far-field limits of Taylor's equation. An alternate explanation is presented in this paper for surface releases. This explanation assumes that the less-than-linear growth of sigma sub(y) with x is due to the logarithmic wind profile. A simple roughness- and stability-dependent diffusion model based on this explanation is shown to compare well with field measurements of sigma sub(y). In neutral conditions, the model indicates that sigma sub(y) should be proportional to x super(0.86) and z sub(o) super(0.14), where z sub(o) is the roughness length.

AN - 16884122; 3579972 AB - Postincubation differential filtration (PIDF), preincubation differential filtration (Pre-IDF), and track autoradiography (TA) were compared for estimating cell-specific and total photoautotrophic picoplankton production. Experiments were performed in Lakes Michigan and Huron and in the Gulf of Mexico. When Synechococcus dominated the photoautotrophic picoplankton community (>70% of total picoplankton abundance), PIDF estimates of cell-specific and total picoplankton production were similar to 3.0 x (range, 2.0-3.8 x) higher than TA estimates. PreIDF estimates of cell-specific and total picoplankton production, however, were only slightly higher than TA estimates (mean, 1.4 x; range, 1.4-1.5 x). The higher PIDF estimates were attributable to breakage and damage of larger photoautotrophs during postincubation filtration and to retention of this labeled material on the smaller (0.2 mu m) pore-size filter. Results from PIDF experiments must be viewed with caution and previous estimates of picoplankton production, cell-specific or total, based solely on PIDF may need to be re-evaluated.

Aside from storms, winds over the continental shelf in Onslow Bay blew predominantly along-shore with velocities approaching 14 m/s during February and March 1986, and January and February 1989. Water masses and currents observed at two current-meter morings, one at mid-shelf and the other on the outer shelf, reflected the onshore (or offshore) advection of interior water in compensation for the offshore (or onshore) advection of wind-driven surface water. Winds and currents reversed direction approximately every 4 to 6 days. The larvae of Atlantic menhaden, Brevoortia tyrannus, spot, Leiostomus xanthurus, and Atlantic croaker, Micropogonias undulatus, were most abundant in 17-19 degree C and 20-21 degree C water of the outer shelf and Gulf Stream fronts. There was little indication of diel vertical migration; larval Atlantic menhaden were most abundant in mid- and surface water, while spot and Atlantic croaker were most abundant in mid- and deep water. Given this distribution, the inferred advective transport larvae was at times onshore, but at other times it was offshore. Within a spawning season, the prevalence of either reciprocation could determine the number of larvae that reach coastal inlets.

Atlantic menhaden appear to spawn in a relatively less-predictable environment. Compared with gulf menhaden, Atlantic menhaden are older at the onset of sexual maturity and have a longer reproductive span, as well as a longer spawning period. Atlantic menhaden produce larger eggs, and their larvae are larger at hatching and younger and larger at first feeding; the larvae appear to grow faster but they are relatively smaller than gulf menhaden at their first metamorphosis. Heavy exploitation of Atlantic menhaden has resulted in a truncation of the age structure, contraction of their spawning range, a reduction in lifetime fecundity, and possibly modifications of the egg size distribution. Thus, the risk of reproductive failure may have increased because spawning now takes place over narrower geographic and temporal ranges.

These were combined with monthly average surface observations and used in a surface energy balance model to estimate monthly mean evapotranspiration at each site. The modeled evapotranspiration and surface energy fluxes are reasonable. The nature of the surface energy balance model is such that it can be solved with satellite measurements and numerical weather forecast model output alone. This suggests that large-scale evapotranspiration climatologies can be made without in situ observations. JF - Journal of Climate AU - Tarpley, J D AD - Satellite Res.

From July through September 1993, an experimental observational product to identify convective activity within 30 n mi of six airports from southern Virginia to Delaware was transmitted three times each hour to personnel at Weather Service Offices and Center Weather Service Units and to the meteorologists and flight dispatchers of five major air carriers. This user-oriented evaluation and the associated statistical analysis has provided important feedback to assess the utility of the product as a supplement to ASOS. Integration of information from several products generated by the new Doppler radar at Sterling with lightning network data is being pursued for the second phase of the project. The National Weather Service will determine the viability of this approach to generate products to routinely supplement the information provided by ASOS on either a national or a local basis.

Current knowledge of toxicant exposure and associated biological effects in marine fish from this region will be reviewed and used to evaluate how conditions have changed since intensive sampling began in the 1970s. Also discussed are possible relationships between toxicant-associated disease in individual fish and changes in fish abundance. Finally, on the basis of current evidence the authors will attempt to provide some recommendations as to those types of impact which appear to be the most serious and are particularly in need of attention in future research and monitoring studies in the US/Canada transboundary region.

At all other times the EPR was nearly zero. Each pulse in egg production initiated a distinct cohort. Survivorship from egg to adult was low: 3% for the first cohort and 0.8% for the second. The third cohort did not reach maturity. Mortality was highest in the egg stage - only 10% of the eggs produced survived to first nauplius. Rates of egg mortality were positively correlated with clearance rates of T. longicornis, suggesting cannibalism as a cause of high mortality. However, the clearance rates required would be similar to 34-fold too high, suggesting a different density-dependent factor, such as disease, viruses, ecto-parasitism or consumption by dinoflagellates. Advection and resting egg production do not appear to explain high rates of egg loss.

In so doing, they sample from a variety of production and trade arrangements. Consequently, numerous arrangements may co-exist, perhaps for extended periods. An important dimension of such arrangements is their duration. Consider, for example, a coastal state that seeks to uncover a latent comparative advantage in fishing and, thus, forms a co-operative fishing arrangement with a foreign partner through which virtually all fishing decisions are made by that partner under a long term contractual arrangement. The planned life of that arrangement will influence the extent to which the potential yield of the resource is husbanded by the foreign partner. This, in turn, will determine the long term success with which the coastal country develops its comparative advantage in fishing. As a consequence, the terms of co-operative fishing contracts may be designed to address equity issues. These are different from, but not necessarily independent of, efficiency issues. This is particularly true when partners discount the future at different rates. It is important for the analyst to be aware of these efficiency and equity issues and how they relate to each other.

Development was divided into 21 stages. A piecewise regression model with midpoints of each stage describes the relation between time to each stage of development and temperature. Preserved eggs of each stage are described, illustrated, and photographed. Midpoint of hatch was 393 hours at 3.8 degree C, 303 hours at 5.7 degree C, and 234 hours at 7.7 degree C. Mean length of larvae at hatch increased linearly with temperature. We compared rate of development, time to 50% hatch, and morphological development with other studies of walleye pollock eggs. Rate of development and time to 50% hatch were similar among populations of eastern North Pacific walleye pollock. Western North Pacific walleye pollock required longer incubation times than eastern North Pacific walleye pollock. Morphological development of Shelikof Strait eggs differs from development of western North Pacific walleye pollock eggs: optic vesicles, myomeres, eye lenses, heart, and otic capsules appear earlier than in Shelikof Strait eggs, and eye pigment appears later. The differences in development may be exacerbated by the condition of the eggs in which they were examined (e.g. preserved vs. live). Developmental differences between stocks are discussed with the conclusion that model components for egg mortality and spawning biomass must be based on specimens collected in the area of interest.

The model is a general circulation model of the coupled ocean-atmosphere-land surface system, with a global computational domain, smoothed geography, and seasonal variation of insolation. The simulated increase of sea-surface temperature is very slow in the northern North Atlantic and the Circumpolar Ocean of the Southern Hemisphere where the vertical mixing of water penetrates very deeply and the rate of deep water formation is relatively fast. Extending this work, we investigated the transient responses of the coupled model to the doubling and quadrupling of atmospheric CO sub(2), over the period of several centuries. During the entire 500-yr period of the experiment, the global mean surface air temperature increases almost 3.5 degree C when CO sub(2) is doubled, and 7 degree C when it is quadrupled. In the latter experiment, the thermal structure and dynamics of the model oceans undergo drastic changes, such as cessation of the thermohaline circulation in most of the model oceans, and substantial deepening of the thermocline, especially in the North Atlantic. These changes prevent the ventilation of the deeper layer of the oceans and, if they occurred in reality, could have a profound impact on the carbon cycle and biogeochemistry of the coupled ocean-atmosphere system.

Eighty-six percent of the 78 seals' stomachs examined contained fish. Other prey taxon groups, in decreasing order of their percentages of occurrence, were crabs (73%), clams (55%), snails (47%), amphipods (32%), shrimp (18%), mysids (13%), marine worms (13%) and cephalopods (4%). The most frequently occurring prey species were capelin, Mallotus villosus (82%); codfishes, Gadidae (64%); narrow snow crab, Chionoecetes opilio (63%); eelpouts, Lycodes spp. (56%); longsnout prickleback, Lumpenella longirostris (49%); nutshell clams, Nuculana sp. (42%); and moon snails, Polinices sp. (27%). Seventy-seven percent of the seals examined had consumed prey from three or more different taxon groups. We identified seven food items not previously reported as prey of the bearded seal in the Bering Sea. No differences were detected between the diets of males and females and between adults and juveniles, indicating no apparent segregation of foraging by sex or age. Bearded seals in the St. Matthew Island region of the Bering Sea forage in a manner similar to their conspecifics in other areas where fish constitute a major portion of their diet. Prey selection is probably dependent on availability, and diet may be highly diversified even within a relatively small area during a short period of time. Variety in prey consumption exemplifies the ability of the bearded seal to forage in the seasonally changing habitat associated with the advance and retreat of the ice front.

To achieve the required spatial coverage, the GPCP uses simple rainfall estimates derived from IR and microwave satellite observations. In this paper, we describe the GPCP and its first Algorithm Intercomparison Project (AIP/1), which compared a variety of rainfall estimates derived from Geostationary Meteorological Satellite visible and IR observations and Special Sensor Microwave/Imager microwave observations with rainfall derived from a combination of radar and raingage data over the Japanese islands and the adjacent ocean regions during the June and mid-July through mid-August periods of 1989. To investigate potential improvements in the use of satellite IR data for the estimation of large-scale rainfall for the GPCP, the relationship between rainfall and the fractional coverage of cold clouds in the AIP/1 dataset is examined. Linear regressions between fractional coverage and rainfall are analyzed for a number of latitude-longitude areas and for a range of averaging times. The results show distinct differences in the character of the relationship for different portions of the area. In general, to the south and east of the mountainous axis of Japan, rainfall and fractional coverage are highly correlated for thresholds colder than 245 K, and correlations can be increased by averaging in space and in time up to the dominant period of the precipitation events. To the north and west of the axis, the correlations between rainfall and fractional coverage, while generally smaller for all scales, are highest for thresholds warmer than 245 K. The proportional coefficients relating rainfall to fractional coverage at cold thresholds, however, differ greatly between the two periods and both differ significantly from those found for the GARP (Global Atmospheric Research Program) Atlantic Tropical Experiment. These results suggest that the simple IR-based estimation technique currently used in the GPCP can be used to estimate rainfall for global tropical and subtropical areas, provided that a method for adjusting the proportional coefficient for varying areas and seasons can be determined.

In addition to the standard integration in which the atmospheric concentration of carbon dioxide remains unchanged, two integrations are conducted. In one integration, the CO sub(2) concentration increases by 1%/yr (compounded) until it reaches four times the initial value at the 140th year and remains unchanged thereafter. In another integration, the CO sub(2) concentration also increases at the rate of 1%/yr until it reaches twice the initial value at the 70th year and remains unchanged thereafter. During the 500-year period of the doubling and quadrupling experiments, the global mean surface air temperature increases by about 3.5 degree C and 7 degree C, respectively. The rise of sea level due to the thermal expansion of sea water is about 1 and 1.8 m, respectively, and could be much larger if the contribution of meltwater from continental ice sheets were included. It is speculated that the two experiments described above provide a probable range of future climate change. JF - Journal of Climate AU - Manabe, S AU - Stouffer, R J AD - Geophys. Fluid Dyn.

The larval density in nighttime quantitative samples was calculated and ages determined from otolith microstructure. Back-calculated birthdates and larval abundance data were used to estimate the relative contribution of weekly age cohorts to seasonal recruitment of larvae. Summaries of these data were measures of the spawning distributions. Larvae were recruited to the estuary from mid-November through April, with about 86% collected during February-April. In all years, age and size of larvae increased linearly throughout recruitment until the end of March and then declined. The mean age of recruited larvae over all years was 61 days and the mean standard length was 24.6 mm. Atlantic menhaden spawning season was protracted, lasting 4-6 months. In every spawning season, a dominant birthweek mode in either December or January contributed from 25-43% of the total recruits. More than 76% of all spawning occurred in the December-January period. Individual birthweek cohorts recruited to the estuary over periods from one week to several months. Cohorts that usually contributed the greatest number of individuals to estuarine recruitment usually recruited over longer periods. Atlantic menhaden have apparently selected a spawning season and location that ensures transport of larvae across the southeast United States continental shelf and arrival of most larvae during a time when conditions are conducive to optimal survival in the estuary.

This paper reviews the logistic production model, starting with the basic differential equation and continuing with a description of the model development without the equilibrium assumption. It then describes several extensions, including "tuning" the model to a biomass index; partitioning fishing mortality by gear, time, or area; and making projections. Computation of confidence intervals on quantities of interest (e.g. maximum sustainable yield (MSY), effort at MSY, level of stock biomass relative to the optimum level) can be done through boot-strapping, and the bootstrap can also be used to construct nonparametric tests of hypotheses about changes in catchability. To fit the model, an algorithm that uses a forward solution of the population equations can be implemented on a small computer. An example of the utility of surplus-production models (illustrating several of these extensions) is given. The example is loosely based on swordfish (Xiphias gladius) in the North Atlantic Ocean, but is not intended to describe the actual status of that stock.

By fitting a fish movement model to the tag data, we were able to estimate mortality and movement parameters (including diffusivity), parameters of a function that models FAD attraction, and a separate parameter of island attraction. Diffusivity was high enough to effectively distribute fish throughout the island archipelago (approximately 150 000 km super(2)) within a few months. Estimates of FAD parameters indicate that the presence of up to four or five FADs in an area approximately 50 x 50 km can reduce the propensity for skipjack to leave that area by approximately 50%, but that deploying additional FADs in such an area does not significantly increase their effectiveness in holding skipjack. Estimates of the island attraction parameter imply that the propensity of skipjack for movement away from the archipelago is less than half the propensity for movement within it.

Describing the uncertainty can be important in allowing managers to weigh the benefits and losses of different management strategies and to allay concerns about the effects of process, measurement, and model errors on the scientific advice, even if a formal decision theoretic risk analysis has not been carried out. The four general steps in analyzing uncertainty and assessing risk are estimation of the uncertainty in the assessment of current stock status due to measurement error, evaluation of the impacts of potential model errors on the assessment, stochastic projections incorporating estimation error and process errors to investigate the impacts of different management options, and assessment of risk using simple utility functions. At least one of these steps has been included in assessment analyses of about 20 major U.S. fisheries. All of these steps have been incorporated in the scientific advice on a few fisheries to date and should be attempted whenever possible to improve the information available to fishery managers.

We speculate that iodine chemistry in combination with trends in anthropogenic chlorine and bromine may also be a factor in determining the widespread current depletion of lower stratospheric ozone. We also speculate on a related role for iodine in the sudden springtime surface ozone loss observed in the Arctic. JF - Journal of Geophysical Research. D.

A previous study evaluated morphological variation in skull morphology, but now specimens are available for a greater portion of the range. Also, corrections have been made in data and an assessment has been made evaluating repeatability of character measurements. We reassessed geographic variation in 30 cranial features (26 morphometric measures and 4 tooth counts) based on 611 museum specimens. All characters except two tooth counts showed statistically significant geographic variation, while 21 of the 30 characters exhibited significant sexual dimorphism. Males were larger in most characters; females were larger in some length measurements involving the rostrum and ramus. As in previous analyses, inshore S. attenuata were found to be very distinctive, so subsequent analyses focused on offshore spotted dolphins from 29 5 degree -latitude-longitude-blocks. Mantel tests and matrix correlations for 19 of the 30 features demonstrated significant "regional patterning," whereas 22 of the characters were shown to have "local patterning." Principal-components, canonical-varieties, and cluster (UPGMA and function-point) analyses also were employed to assess geographic variation. In the eastern portion of the range, the subdivision between northern and southern offshore S. attenuata found in the previous investigation was confirmed. In general, blocks to the west (including one encompassing part of the Hawaiian Islands) were more like the southern blocks than those of the northeast. Morphological patterns were similar to those found in a number of environmental variables, particularly water depth, solar insolation (January), sea surface temperature (January and July), surface salinity, and thermocline depth (winter and summer). Present management units are inconsistent with the pattern of cranial variation; spotted dolphins from west of lat. 120 degree W probably should not be pooled with those to the east, as they show closer affinity with the southern offshore unit. In addition, the boundary between the northern and southern units should probably be moved north to about Lat. 5 degree N.

The procedure for calculating the applicable reactive uptake coefficients using laboratory-measured parameters is developed, the necessary laboratory-measured quantities are discussed, and a set of equations for use in models are presented. This approach is demonstrated to be essential for obtaining uptake coefficients for the HOCl+HCl and ClONO sub(2)+HCl reactions applicable to the stratosphere. The measured uptake coefficients for N sub(2)O sub(5)+H sub(2)O and ClONO sub(2)+H sub(2)O as well as those for other heterogeneous reactions are discussed in the context of this model. Substantial direct chlorine activation and consequent ozone destruction is shown to occur due to heterogeneous reactions involving HCl for volcanically perturbed aerosol conditions at high latitudes. Smaller but significant chlorine activation also is predicted for background aerosol loadings at extreme high latitudes, suggesting chlorine activation can occur on background sulfuric acid aerosol in these regions. The coupling between homogeneous and heterogeneous chemistry is shown to lead to important changes in the concentrations of various reactive species. JF - Journal of Geophysical Research. D.

The function is used to develop a model in which both gamma and the natural mortality rate M are formally indeterminate and in which the coming year's catch limit can be viewed as a response function of either estimated gamma or estimated M. Decision theory is then used to derive the optimal catch. The optimal catch is shown to increase with the degree of uncertainty surrounding M, although this conclusion may depend on the short managerial time frame assumed. Three "suboptimal" strategies are also considered: (1) setting catch at the level corresponding to the expected value of M, (2) setting catch at the minimum of the response function, and (3) setting catch at the level corresponding to gamma = 0. The first suboptimal strategy never results in a catch greater than the optimum and always results in a lower expected loss than the second. The performance of the third strategy (relative to the others) depends on parameter values. JF - Canadian Journal of Fisheries and Aquatic Sciences AU - Thompson, G G AD - U.S. Dep.

In 1986, a model evaluation showed that the RELMAP overestimated total sulfur wet deposition for the warm seasons by 25-35%, partly due to subgrid-scale variability in the observed precipitation fields. Refinement of the model grid to fully resolve the precipitation observation network would increase the computational requirements of the model to unacceptable levels. Instead, a new parameterization for the wet removal fraction was implemented in hopes of reducing the model's sensitivity to precipitation variability. The effects of observed sub-grid-scale precipitation variability on SO sub(2) and SO sub(4) super(2-) wet removal in the original and updated RELMAP have been isolated and analysed.

I: Research vessel surveys, 1986-1990 AN - 16827537; 3563820 AB - We used canonical correspondence analysis (CCA), an eigenvector ordination technique that includes direct gradient analysis, to investigate habitat use by spotted, Stenella attenuata, spinner, S. longirostris, striped, S. coeruleoalba, and common, Delphinis delphis, dolphins in the eastern tropical Pacific during 1986-1990. Data were collected during annual research vessel cruises conducted in August-November of each year. Environmental variables included in the analyses were surface temperature, salinity, sigma-t, and chlorophyll, and thermocline depth and thickness. The dominant pattern in the species-environment relationship (1st canonical axis) separated common dolphins from spotted and spinner dolphins, based on their associations with cool upwelling habitat and warm tropical habitat, respectively. The second axis separated whitebelly spinners from eastern spinner dolphins. Both occurred in tropical water, but were separated primarily by thermocline topography. The species-environment correlations were 0.67 on the first axis, 0.42 on the second. Overall, the environmental data explained 15% of the variance in the species data. For individual school types this ranged from 36% for common dolphins to 6% for striped dolphins. Interannual variability in the species data was small but was judged significant by a Monte Carlo randomization test.

Declines in density occurred mainly at sites in the southeastern portion of the lake where unionids were highly infested with D. polymorpha. Unionid densities at highly infested sites declined from 2.4/m super(2) in 1986, to 1.8/m super(2) in 1990, and to 0/m super(2) in 1992. While the mean number of D. polymorpha per unionid was < 1 at these lightly infested sites in 1990, it increased to 35 by 1992. Given this relatively slow increase in D. polymorpha per unionid in this portion of the lake, continued monitoring of populations should provide a better understanding of the relationship between the extent of infestations and unionid mortality.

More than 10,000 juvenile salmon were caught in 252 purse-seine sets during August 1983, July 1984, and August 1984. Distribution was patchy; juvenile salmon were highly aggregated, rather than dispersed randomly. Distribution and size of pink salmon (O. gorbuscha), sockeye salmon (O. nerka), and chum salmon (O. keta) were similar but differed from coho salmon (O. kisutch). Chinook salmon (O. tshawytscha) were excluded from most analyses because few were caught. Sizes were consistent with the concept that juvenile salmon in more northern and seaward locations had been at sea longer than those in more southern and inshore locations. Juvenile salmon migration up the Pacific coast did not peak in abundance off Southeast Alaska until August; movement from inside to outside waters was not complete by the end of August. The migration band of juvenile salmon in outside waters of Southeast Alaska extended beyond the continental shelf to at least 74 km offshore, twice the distance previously reported.

The break-and-burn method of age determination is difficult to apply to sablefish. Therefore, we applied a relatively new method of fish age validation, using the disequilibrium of Pb-210/Ra-226 in the otoliths. This method of validation complements previous methods which used oxytetracycline (OTC) marking to validate incremental growth in sablefish otoliths. The Pb-210/Ra-226 disequilibria generally confirmed the ageing criteria used to interpret the otolith's burnt cross-section.

These were made with ground-based and airborne weather radars at nearly vertical incidence. A sharp decrease of | sub( rho hv)(0)| occurs at the bright band bottom, and is attributed to a varying mixture of hydrometeors with diverse shape, size, and thermodynamic phase. The largest contribution to decorrelation seems to come from wet aggregates; this is substantiated by consideration of two simple models. One consists of randomly oriented wet prolate spheroids, and the other considers an ensemble of distorted spheres. Prolates with axis ratios of 3 or distorted spheres with rms roughness equal to 15% of the diameter decrease the correlation to 0.8 at S band. At Ku band and for the size range encountered in the bright band, the decrease is a function of equivalent diameter because scattering is in the Mie regime. | sub( rho hv)(0)| measurement at 13.8 GHz and from the aircraft are the first ever. Also, differential phase and differential reflectivity at a 10 degree off nadir are the first of its kind. These last two variables showed a distinct signature in the bright band. This is significant because it might lead to applications on airborne or spaceborne platforms.

AN - 16805578; 3555760 AB - Hydrofluorocarbons, many of which contain a CF sub(3) group, are one of the major substitutes for the chlorofluorocarbons and halons that are being phased out because they contribute to stratospheric ozone depletion. It is critical to ensure that CF sub(3) groups do not cause significant ozone depletion. The rate coefficients for the key reactions that determine the efficiency of the CF sub(3) radical as a catalyst for ozone loss in the stratosphere have been measured and used in a model to calculate the possible depletion of ozone. From these results, it is concluded that the ozone depletion potentials related to the presence of the CF sub(3) group in hydrofluorocarbons are negligibly small.

Most larvae were found in the upper 45 m of the water column throughout the diel period but were concentrated in higher densities near the surface (0-15 m) n daylight hours and at greater depths at night. Four of the five dominant taxa examined in detail showed significantly greater weighted mean depths during the night than during the day. This pattern was the opposite to that previously reported for the numerically dominant taxa (Theragra chalcogramma) in this area. Since there was no clear relation between the diel vertical distribution of these taxa and the vertical distribution of water temperature and density or copepod nauplii prey, we hypothesize that this reverse migration is either a strategy to minimize spatial overlap with predators that follow a normal diel migration pattern or one to optimize light levels for feeding.

Effects on abundances estimated from tuna vessel sightings, 1975-1990 AN - 16804201; 3551974 AB - The results of a canonical correspondence analysis (CCA) of data from research vessel surveys of the eastern tropical Pacific were applied to time series of estimated dolphin abundances from tuna vessel sightings. The research vessel survey data consisted of daily dolphin school sightings and concurrent environmental variables for August-November of 1986 through 1990. Seasonal field of habitat quality for 1975-90 were calculated from historical bathythermograph data by using the CCA ordination results. For spotted (Stenella attenuata) and eastern spinner (S. logirostris orientalis) dolphins, annual abundance estimates or interannual changes in those estimates are significantly correlated with habitat quality. This effect is at least partly due to expansion of high quality habitat beyond the geographic ranges assumed for the abundance estimate. We discuss ways that environmental data could be used to reduce error in dolphin abundance estimates. JF - Fishery Bulletin AU - Fiedler, P C AU - Reilly, S B AD - Southwest Fish. Sci.

Sampling extended from Cape Sable, Nova Scotia to Cape Hatteras, North Carolina during eight surveys from June 1984 to April 1985. Twenty-four taxa were analyzed for evidence of extrusion by comparing the standardized abundances between the two plankton nets. The mean estimated abundance under 10 m super(2) of sea surface for all taxa combined was 54% higher in the 0.333 mm net. The difference in catches between nets occurred primarily in the 2 to 5 mm length range, indicating that the smaller larvae were extruded through the 0.505 mm mesh net.

Fur seals were collected from August to October of 1981, 1982, and 1985. Juvenile walleye pollock (Theragra chalcogramma) and gonatid squid were the primary prey. Pacific herring (Clupea pallasi) and capelin (Mallotus villosus), considered important fur seal prey in previous reports, were absent from the diet. Prey species and size varied among years and between nearshore and pelagic sample locations. Interannual variation in the importance of pollock in the diet of fur seals was positively related to year-class strength of pollock. Midwater (n=23) and bottom (n=116) trawls were conducted at the location of fur seal collections to determine availability of fish and squid relative to prey species eaten by fur seals. The species and size composition of prey taken by fur seals was similar to midwater trawl collections, but differed from bottom trawl catches. Contrary to earlier conclusions that northern fur seals are opportunistic in their feeding habits, we conclude that fur seals are size-selective midwater feeders during the summer and fall in the eastern Bering Sea.

Methods of reporting and comparing proximate composition are discussed. Examination of measurements presented in a number of published papers, using allometric analysis, indicates that comparison of proximate compositions on a dry weight basis and failure to include fish size as a covariate have, in many cases, led to erroneous conclusions concerning the effects of environmental and dietary factors on the proximate composition of cultured fishes. Available evidence indicates that the protein content of growing salmonids is determined solely by fish size (is endogenously controlled), that lipid level is effected by both endogenous and exogenous factors, that ash content is homeostatically controlled, and that whole body moisture is inversely related to body lipid. The implications of the present findings to nutrition studies and the potential for modification of carcass composition in cultured fish are discussed.

Specimens were captured from the western, central, and eastern North Pacific between approximately lat. 38 degree N and 47 degree N by driftnet fishing, trawling, and jigging in the summers of 1990 and 1991. Results suggest that increments were deposited at a rate of one per day. Both sexes live approximately one year; males mature at smaller sizes and younger ages than females. Exponential growth models suggest that growth in length was similar for males and females (0.80% ML/day) in the central North Pacific, while growth in weight was higher for females (1.90% WT/day) than males (1.40% WT/day). Females in the western North Pacific exhibited faster growth rates than individuals from the central North Pacific. O. borealijaponica were estimated to have hatched year round based on back calculation of statolith increments from the time of capture. Post-recruit individuals exploited in the O. borealijaponica jig fishery and Ommastrephes bartramii driftnet fishery typically hatched from late summer to early winter.

There are two identifiable stocks of king mackerel in the Gulf of Mexico: a western stock and an eastern stock. The western stock migrates northward along the Mexico-Texas coast during the spring and early summer from its winter grounds in Mexico (Yucatan Peninsula). This stock has a high frequency of the dipeptidase PEPA-2*a allele. The eastern stock migrates at the same time northward along the eastern coast of the Gulf of Mexico from its winter grounds in south Florida (Gulf of Mexico and Atlantic coast). This stock has a high frequency of the dipeptidase PEPA-2*b allele. Both stocks migrate simultaneously into the northern Gulf of Mexico and mix at varying degrees in the northern summering grounds (Texas to northwest Florida).

Recent studies have documented dense populations on seamounts of the South Atlantic and North Pacific. At Southeast Hancock Seamount, a small guyot in the Central North Pacific, M. muelleri populations are mainly composed of juveniles. Seasonal length frequencies suggest that recruitment at sizes greater than 20 mm standard length (SL) occurs principally in spring and summer months, with growth over summer and fall coincident with decreasing abundances. Mature fish in reproductive condition occur in winter months but do not survive to the following spring; they also may be too few at this small seamount to support annual recruitment. Potential sources of additional recruitment include populations at several larger seamounts in the southern Emperor group and also the large populations around Japan. Advection of eggs and larvae in the Kuroshio Extension may provide recruits for dependent populations at the seamounts. Mean current flow and satellite-tracked drifters suggest a transit time of 100-200 days from the coast of Japan to the region of the seamounts; estimates of age at length suggest that smaller fish have similar ages at recruitment. Gill-raker counts, however, differ between Japanese and seamount populations. We suggest that the southern Emperor Seamount populations serve as the source for replenished annual recruitment to the small population at Southeast Hancock Seamount.

Following removal of 80% of the adult white sucker population, the composition of somatic tissue of adult yellow perch collected from mid-April to mid-July improved, with water content decreasing and fat and caloric contents increasing. In a nearby reference lake, yellow perch proximate composition showed either no change or became less favorable during the same time period. From mid-July to mid-October, somatic tissue composition showed no improvement in Douglas Lake; this is consistent with a previous study showing that feeding rate late in the summer was not significantly different after sucker removal. Gonadal development had a strong influence on the composition of somatic tissues. Immediately following spawning, fat and energy reserves were depleted and the water content of somatic tissues was high. During the summer (May through August), yellow perch stored fat and energy in somatic tissues, and their body water contents decreased in both lakes. Both sexes of yellow perch began gonad development during September and showed concurrent declines in fat and energy content in somatic tissues. Male yellow perch completed gonad development by mid-October, whereas gonadal development in females continued until spawning in late April. Male and female yellow perch showed similar rates of decline in fat and energy content during the winter, even though females were developing gonadal tissue during this time and males were not. Because female yellow perch required additional energy for gonadal development during the winter but showed a rate of somatic energy depletion similar to that of males, it appears that female yellow perch either rely on feeding or use energy-saving behaviors during the winter to supply the additional energy required for gonadal development. The improvement we observed in yellow perch body composition following white sucker removal indicates that fish respond to reductions in competition with qualitative changes in proximate composition as well as with quantitative changes in growth.

VICBAR is compared to the other operational hurricane track forecast models and is shown to perform as well as each of these. VICBAR forecasts are stratified by initial date, intensity, and location to assess the variability of model performance. VICBAR produces the best forecasts for hurricane cases, for cases initiated earliest in the hurricane season, for cases moving the most slowly northward, and for those moving westward. The forecasts with the largest errors are examined to illustrate the limitations of the model and to determine whether these cases can be identified operationally.

Persistent landward and net northward flow characterized the circulation of near-surface waters during the larval periods studied. A mechanism for progressive seaward transport of larvae through ontogeny, as proposed by others, was not apparent. Overall, above- (below-) average year classes were associated with relatively weak (strong) northward transport and, to a lesser degree, strong (weak) landward transport. Based on these analyses and in consideration of the prevailing coastal circulation, we propose that the relative magnitude of C. magister juvenile recruitment and, hence, incoming year class strength, reflects: (1) the proportion of larvae retained within a relatively narrow ( less than or equal to 15 km) and heterogeneous 'coastal landing strip', (2) the availability of suitable substrate within the coastal landing strip at time of settlement and (3) the magnitude of downstream advective losses (export) of larvae from the California-Oregon-Washington coastal system. Based on a consideration of the physics of the California Current system and the larval biology of the species, significant linkage of Dungeness crab populations along the west coast of North America is likely.

Statistics on the number of flashes, location, polarity, peak currents, and multiplicity (number of strokes per flash) are examined in an 18-h period divided into prelandfall and postlandfall categories. Land-based and aircraft lower fuselage radar data are also analyzed to determine the nature of the precipitation in which lightning is detected. Jerry is found to be more electrically active than Hugo, with 691 flashes detected compared with 33 flashes for Hugo. The majority of these flashes, regardless of the polarity, are located in the right front and right rear quadrants of the hurricanes, almost exclusively in outer convective rainbands. One reason for the large difference in the number of flashes between the two storms is the presence of many convective rainbands in Jerry, compared to only a few in Hugo. More than 20% of the flashes in each storm have a positive polarity. Median negative peak currents of the first return strokes are 49 kA in Hugo and 40 kA in Jerry. Median positive peak currents are 65 kA in Hugo and 52 kA in Jerry. The mean multiplicity of the negative flashes is 1.7 in Hugo and 2.6 in Jerry. Twenty percent of the negative flashes detected in Jerry have a multiplicity of 4 or higher.

In addition, possible changes in partitioning with sediment aging and during bioaccumulation assays were examined. Centrifugation with C-18 separation produced the most consistent partition coefficients. Partition coefficients from filtration and centrifugation methods compared favorably with previously published data. Contaminant partitioning did not change during 96-h exposures in bioassays, and partitioning of contaminants in porewater and elutriates did not follow a linear trend with the amount of sediment aging or manipulation. The contaminant partitioning apparently depends on characteristics of the contaminant as well as contaminant-associated media composition.

We compared length data obtained from vertical aerial photographs of 28 schools of striped dolphins from the northern and southern regions of the eastern tropical Pacific and found no significant differences in average length for adult animals ( greater than or equal to 180cm) or for adult females, defined here as dolphins closely accompanied by a calf. Analyses of back-projected birth dates for dolphins greater than or equal to 155cm revealed a broad pulse in reproduction extending from the fall through the spring; however, sample size was inadequate to compare timing of reproduction between the two areas. Striped dolphins measured from aerial photographs were longer on average than those killed incidentally in fishing operations. We found a pattern of segregation by size between schools that is analogous to the separate schools of juveniles and adults that are found in the western Pacific. We hypothesized that the specimen data base may be biased because tuna purseseine fishermen in the eastern tropical Pacific may selectively set on schools composed of younger, smaller dolphins.

Strains of these species that had been induced to tolerate high Cd concentrations were cultured axenically in artificial seawater media with 15, 60, and 60 mg/liter Cd, respectively. Algal diets consisting of strains of these species cultured in Cd-free medium and containing no measurable Cd served as controls. Algal cells were harvested in a nitrogen deficient stationary phase from semi-continuous cultures and analyzed for Cd uptake. Daily feeding rations of the three algal species listed above contained known quantities of Cd: 41.0, 20.2, and 15.2 mu g/bivalve/day, respectively. Daily algal rations were also analyzed for nutritional components (protein, carbohydrate, and lipid), and significant effects of Cd on algal composition were found. Oysters fed cadmium-contaminated P. tricornutum, D. tertiolecta, or a 50/50 mix of these two species exhibited varied responses. Diets including Cd-contaminated D. tertiolecta caused mortality and weight losses of oysters whereas, oysters fed P. tricornutum cultured in Cd showed no significant effect. Clams fed unialgal diets of Cd-contaminated I. galbana, D. tertiolecta, or P. tricornutum did not grow, but mortality was observed only in clams fed Cd-contaminated P. tricornutum. Differences in bivalve responses to the various algal diets may reflect interactions between Cd toxicity and nutritional factors, especially for oysters in which the toxic effects of Cd were more severe when more digestible diets were fed. These results demonstrate detrimental effects of pollutant-contaminated algae upon consumer species' survival and growth, parameters of fundamental importance to population structure.

Updrafts and downdrafts as strong as 24 and 19 m/s, respectively, were found. Mean updrafts and downdrafts were approximately twice as strong as those found in other hurricanes. Updrafts had approximately the same width as downdrafts. The most vigorous updrafts were located in the front quadrants of the storm, and most of the strongest downdrafts were found in the rear quadrants. The downdrafts could not be explained in terms of evaporative or melting cooling, or precipitation drag. Evidence is presented that moist symmetric instability initiated by precipitation loading may have been responsible for the strong downdrafts.

Bioavailability of a sediment-associated contaminant can be defined by the uptake clearance. Uptake clearance is the volume or mass of the source compartment scavenged of contaminant per mass of organism per time. For non-polar organic contaminants, carbon normalization has been suggested as a means of normalizing the relative bioavailability among sediments of differing compositions. To examine this, amphipods, Diporeia spp., were exposed to five Lake Michigan sediments and one soil from Florissant, MO, each spiked with selected polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) congeners. The uptake clearances (k sub(s)) were then determined. The PAH congeners were generally less bioavailable, based on k sub(s), than the PCB congeners after accounting for contaminant hydrophobicity. The k sub(s) values generally declined as the fraction of fine particles (<63 mu m) and organic carbon increased among the sediments. Organic carbon normalization reduced the variability among the k sub(s) values to approximately a factor of two among the Lake Michigan sediments, but the Florissant soil was an outlier. The compounds were more bioavailable from the Florissant soil than from the Lake Michigan sediments, and the relative availability increased with increasing contaminant hydrophobicity up to a factor of eight for hexachlorobiphenyl.

We observed no change in pigment content or in a* values after 180 d frozen storage or following a thaw/refreeze cycle compared to fresh fish, even though higher a* values were seen in fillets from fish fed synthetic astaxanthin or canthaxanthin after 90 d frozen storage suggesting that care should be used when interpreting tristimulus color values for grading programs.

Doppler sodars and lidars as well as newly emerging 915-MHz radar wind profiler technology are shown to describe well mean wind and temperature profiles. A number of air quality field research programmes have now deployed these instruments in various combinations in mesoscale experiments. Three studies provide examples for discussion of mean wind and temperature profiles. Unfortunately, many remote sensing instruments have not realized their full potential for measurement of turbulent momentum and heat fluxes as well as mixed-layer depth. A simple four-beam Doppler acoustic system provides a preliminary example of such potential applications. Furthermore, pattern-recognition methods, although subjective in nature, can be applied to time-height cross sections of reflectivity with the data of use in the interpretation of dispersion process in the atmospheric boundary layer.

Furthermore, rather ad hoc assumptions have been made when modeling landfall. The general consensus is that energy supplied primarily through surface fluxes is necessary for tropical cyclone development and maintenance. In the past, rather a priori assumptions have been made such as the elimination of surface sensible and latent heat fluxes over land or the reduction of surface land temperature. By incorporating an improved version of the Geophysical Fluid Dynamics Laboratory (GFDL) tropical cyclone model with diurnal radiation and a bulk subsurface layer with explicit prediction of land temperature, a series of experiments was performed to test the sensitivity of surface boundary conditions to tropical cyclone development and decay at landfall. A triply nested version of the GFDL model was used in an idealized setting in which a tropical disturbance, taken from the incipient stage of Gloria (1985), was superposed on a uniform easterly flow of 5 m s super(-1). A control case was performed for ocean conditions of fixed 302-K SST in which the initial disturbance of about 998 hPa developed to a quasi-steady state of 955 hPa after one day of integration. Using identical atmospheric conditions, a series of experiments was performed in which the underlying land surface was specified with different values of thermal property, roughness, and wetness. By systematically changing the thermal property (i.e., heat capacity and conductivity) of the subsurface from values typical of a mixed-layer ocean to those of land, a progressively weaker tropical system was observed. It was found that the initial disturbance over land failed to intensify below 985 hPa, even when evaporation was specified at the potential rate. The reduction of evaporation over land, caused primarily by the reduction of surface land temperature near the storm core, was responsible for the inability of the tropical disturbance to develop to any large extent. Under land conditions, the known positive feedback between storm surface winds and surface evaporation was severely disrupted. In sensitivity experiments analogous to the all-land cases, a series of landfall simulations were performed in which land conditions were specified for a region of the domain so that a strong mature tropical cyclone similar to the ocean control case encountered land. Again as in the all-land case, the demise of the landfalling storm takes place due to the suppression of the potential evaporation and the associated reduction of surface temperatures beneath the landfalling cyclone. Even when evaporation was prescribed at the potential rate, a realistic rapid filling (36 hPa in 12 h) ensued despite the idealized nature of the simulations. Although not critical for decay, it was found that surface roughness and reduced relative wetness do enhance decay at landfall.

Cultures in the logarithmic and stationary growth phases were each tested in three ways: 1) live cells against live cells; 2) live cells against medium previously used to grow each algal strain; 3) live cells against medium-soluble cellular extracts of each algal strain. In shellfish aquaculture, the most favorable of situations would be to grow algal strains that are nutritious to shellfish and that grow densely. Algae that exhibit allelopathy should be more successful at resisting culture contaminants and therefore would be more dependable to culture for shellfish food. Further, by selecting out of these the strains that exhibit antibiotic abilities, against undesirable and contaminating bacteria, the shellfish cultured should be healthier.

These confrontations are furthered by competition for access to habitat of declining populations. Confrontations are often in inverse relationship to the level of government involved although all are experiencing difficulty. These circumstances, individually and collectively, indicate a need for a national policy on aquaculture. It should reflect the "state-of-the-art" on this topic and contain an appreciation of traditional fishing activities. The policy should provide guidance for siting, design and operation of aquaculture operations and assurances that competing uses are given full and equal consideration. To establish this policy, proponents of aquaculture should network and develop the kills necessary to influence public opinion.

Cultured and wild juvenile oysters from Oyster and Peconic Bays on Long Island, NY, were also collected in July and September. All were examined for mortality, size, and presence of conchiolin in live and dead oysters. A clear relationship was seen between the presence of conchiolin and mortality. The highest prevalence was seen in dead oysters (70-100%), but high levels were also seen in surviving oysters (14-60%). The presence of conchiolin diminished after mortality stopped and calcified lesions which matched shell checks were apparent. Primary shell checks usually measured 15-19 mm, comparable to size at the initial mortality period. Secondary and tertiary shell checks were evident in some older oysters. Conchiolin and healed shell lesions also were found in fresh boxes 70-112 mm in length. Four percent or less of the 1992 natural set examined from oysters in Peconic Bay exhibited conchiolin. No evidence of JOD was seen in any 1993 natural seed examined in September. JF - Journal of Shellfish Research AU - Farley, CA AU - Lewis, E J AD - NOAA/NMFS, Northeast Fish. Sci. Cent., Coop.

Over 50% of seafood harvested from inland waters is from aquaculture, while less than 10% of seafood production from marine waters is of an aquacultural origin. The aquaculture industry continues to grow in the United States at a rate lower than that worldwide. While overall seafood consumption in the U.S. has declined since reaching a peak in 1987, the percent of that consumption contributed by farm-raised seafood product has risen. The National Oceanic and Atmospheric Administration (NOAA) has been involved in aquaculture since the late 1800's. Extensive fishery management responsibilities assumed by the National Marine Fisheries Service (NMFS) led to neglect of commercial aquaculture research. A review of recent policy actions by NOAA and the Department of Commerce show that this decline has been checked. NOAA is now developed an Implementation Plan for Aquaculture which will serve as a planning guide for the next several years. The Implementation Plan will (1) identify opportunities and recommend strategies to strengthen enhancement capabilities, (2) establish criteria for identifying appropriate candidate species for use in commercial and enhancement aquaculture systems, (3) identify opportunities for collaborative system design studies with the private sector or other Federal agencies, (4) identify research parameters for nearshore and offshore culture systems which minimize environmental perturbations, and (5) develop experimental plans to verify the effectiveness of enhancing wild populations with releases of hatchery-reared finfish.

The authigenic-phase glauconite occurs above detection limits only in the core from the hypoxic area. A major increase in glauconite concentration was coincident with the onset ( similar to 1940) of the increased use of commercial fertilizers in the United States. In the same hypoxic-area core, benthic foraminifera species diversity decreases upcore from approximately the turn of the century to the present in a manner concurrent with glauconite and fertilizer increases. A subset of opportunistic benthic foraminifera species, known to become more prominent in stressed environments (i.e., hypoxic), increased upcore from similar to 52% of the total population at core bottom to similar to 90% at core top. These benthic foraminifera population and diversity changes were not apparent in a "control" core outside the area of documented hypoxia. Seaward of the shelf, in the Mississippi Canyon, coincident increases in sediment accumulation rate, percentages of coarse fraction and of organic carbon at core top indicate increased offshelf transport of carbon and other components.

Genetics and biotechnology studies offer additional opportunities for improving desirable characteristics and for investigating heritable and molecular bases of processes including growth, development, survival, and responses to stress, such as pollution and disease. Moreover, in enhancement efforts, there is a need for development of methods to increase the reproductive potential, conserve gene pools, and improve genetic adaptation of species in stressed environments. For example, oysters bred selectively for fast growth at the Milford Laboratory on Long Island Sound are being employed in studies of survival and disease resistance in Maine and New Jersey.

Classification of these isolates to genus or species level was often difficult; application of bifurcating keys using bacterial phenotypic traits frequently produced results that were contradictory to other identification methods. In an attempt to resolve these problems, a database of phenotypic characteristics of known pathogenic species was compiled from the literature. Ninety-six permutations of pairs of computer-aided, numerical-taxonomy programs and clustering techniques contained in the NTSYS-PC software package (Exeter Software, Setauket, New York) were analyzed for their ability to group known organisms in the database into correct phylogenetic groups. The most accurate combinations proved to be K2 or UN5 coefficients clustered with WPGMA or UPGMA. The reliability of the various computer programs wil also be discussed.

While aquaculture promises to play a significant role in international food and nonfood product markets, the role that aquaculture may play in the United States and an international economy is still unfolding. In this presentation an overview of economic and institutional issues that will influence the pattern and rate of development of marine aquaculture in the United States are discussed. Particular emphasis is placed on how these issues may affect the global competitiveness of United States aquaculture products in international markets.

The juvenile softshells set in bottoms mostly from the low tide mark to a distance at least 60 m from shore to depth of at least 1 m; further depths were unexplored. In the Navesink River, densities were high (up to 7,000/m super(2)) nearly everywhere in early July, but declined gradually by about 40% by November, 1993. Densities in the Shrewsbury River were about 2/3 as high. The reduction in densities was not caused by predation, but by many softshells emerging from the bottom and living on the surface for a few weeks before dying. By November, mean sizes of the clams at different sites in the rivers and Raritan Bay ranged from about 15-24 mm. Besides the softshells; oysters, Crassostrea virginica; amethyst gemclams, Gemma gemma; and Atlantic jackknife clams, Ensis directus, also set in unusually high densities. The sets resulted from relatively small spawning stocks of softshells, oysters, and jackknife clams. Setting was also heavy of softshells; oysters; northern quahogs, Mercenaria mercenaria; and bay scallops, Argopecten irradians, in some bays on Long Island and in southern New England.

Studies reported herein evaluate the effects of salinity and selected standard saltwater aquarium medications on transmission and treatment of JOD. Disease transmission to uninfected Horn Point hatchery-reared oysters, mean length 20 mm, was attempted at salinities of 10-26 ppt. Transmission occurred at 20 and 26 ppt, with 60% and 75% cumulative mortalities after 6 weeks exposure. Dead oysters exhibited conchiolinous shell lesions typical of JOD. Mortalities declined with decreased salinity. At 10 ppt, 16% of the oysters died, but no conchiolin was observed. There was no association of a specific bacterium and JOD infections in this study.

M. Flower Hatchery causes no apparent ill effects in juvenile oysters AN - 16735093; 3718536 AB - A Gymnodinium sp. culture was established from an Oyster Bay water sample, taken near the F. M. Flower oyster hatchery on 17 August, 1992. At this time, mortalities from "juvenile oyster disease" were occurring. An experiment was conducted to determine if juvenile oysters exposed to this dinoflagellate exhibited characteristic symptoms of either 1) juvenile oyster disease, ie, conchiolin deposits within the shell, wasting of mantle tissue, and mortality, or 2) degeneration of absorptive cells of the digestive diverticula, as seen in shellfish feeding on certain other dinoflagellates. For the first two weeks, oysters fed Gymno-F filtered actively, but produced abundant pseudofeces; thereafter, normal fecal strands were produced. The other two diets were ingested normally. Shell growth was noted qualitatively in all treatments except the unfed control. After 36 days--approximately the time required for development of juvenile oyster disease symptoms--oysters were sacrificed, observed for abnormal conchiolin deposits, and evaluated histologically. No abnormal conchiolin deposits were found, nor was there any histological evidence of poor health in any fed treatments. Digestive diverticula showed good development in all fed controls, with Gymno-F appearing in slightly better condition than the other fed controls. From these observations we conclude that this isolate of Gymnodinium is not a causative agent of juvenile oyster disease. The refractory period during which oysters produced pseudofeces when fed Gymno-F is consistent with our previous studies of oysters feeding on another dinoflagellate, as is the eventual resumption of normal feeding and growth; this may be related to changes in oyster digestive enzymes.

Phenanthrene was only slightly toxic with 12 plus or minus 3% mortality at the highest sediment dose (0.62 mu mol/g). Failure to attain and maintain toxic residue body burdens, based on a nonpolar narcosis concentration of approximately 6 mu mol/g, accounts for the low mortality. Phenanthrene toxicokinetic parameters were essentially constant among all doses and consistent with previous measures. Sediment concentration was a poor representation of dose for mortality by pyrene. The relative pyrene distribution among the <63- mu m particles increased in the smallest-sized particles at larger doses. An apparent stimulation of pyrene accumulation was observed as a peak in uptake clearance values between sediment concentrations of 0.16 and 0.26 mu mol/g dry sediment. (Uptake clearance is the amount of source scavenged of contaminant per mass of organism per time.) The pyrene particle-size distribution and the variation in kinetics with dose provide a partial explanation for the poor representation of dose by the sediment concentration. The pyrene body burdens provided a good dose response yielding LD50 values of 6.3 (4.6-41.7, 95% C.I.) and 9.4 (7.9-54.2) mu mol/g for two experiments. These values are consistent with the residue concentrations for 50% mortality by a nonpolar narcosis mechanism. Comparing the experimental and predicted equilibrium partitioning-based sediment concentrations for 50% mortality, the equilibrium prediction overestimates the toxic pyrene sediment concentration by approximately a factor of ten. Diporeia behavior, differential particle-size distribution, and kinetic limitations appear as likely reasons for the variation between calculated and observed concentrations required to produce mortality.

Three habitat types (channel edges, willow edges, and debris pools) were sampled at two downstream sites (lower river) and at two upstream sites (upper river) biweekly from May to September and once in November 1989. For most species, fry (age 0) most often used channel edges with little cover, whereas parr (age greater than or equal to 1) almost exclusively occupied willow edges and debris pools. Within the same habitat types, densities were significantly greater for most species and life-history stages in the upper than in the lower river; steelhead parr, with densities similar in like habitats in the upper and lower river, were a notable exception. Peak fry densities (fish/100 m super(2)) were 2,331 coho, 155 steelhead, and 14 sockeye, whereas peak parr densities were 281 coho, 82 steelhead, and 44 Dolly Varden. Mean length of fry and parr of all species was greater in the lower river than in the upper river. With baseline information from this study, fisheries managers can identify strategies to restore fish and habitat that could be impacted by flooding in the Situk River. Hubbard Glacier is expected to advance and dam Russell Fiord by the year 2000, and overflow from the fiord will flood the Situk River, drastically altering fish rearing habitat.

AN - 16730863; 3718496 AB - Differences between response of the bay scallop, Argopecten irradians, and the eastern oyster, Crassostrea virginica, to the dinoflagellate Prorocentrum minimum, led us to consider possible mechanisms by which dinoflagellates affect different bivalves. Juvenile scallops suffered rapid mortality accompanied by damage to adsorptive cells in the digestive diverticula and systemic pathologies characteristic of toxin effects when fed a diet including P. minimum. By contrast, larval and newly post-set oysters grew and developed poorly, but did not experience acute toxic effects, when fed algal diets including P. minimum. Large, dense accumulation bodies (persistent phagolysosomes) were present in digestive diverticula absorptive cells of young oysters fed P. minimum. When older juvenile oysters were exposed to the dinoflagellate, initial response was to filter, but not ingest P. minimum cells for approximately two weeks, after which oysters fed and grew normally, and digestive diverticula appeared healthy. Thus, presence and contents of accumulation bodies should hold clues about digestive interactions between bivalves and this dinoflagellate. Differences in responses of bivalve mollusks to dinoflagellates, such as Prorocentrum, may result from differences in digestive function, specifically the site at which dinoflagellate autolysosomes are digested.

The first two storms are the subject of this study. The entire life cycles of both storms were documented using a single ground-based Doppler radar. Radar reflectivity signatures of updraft summits and Doppler velocity signatures of divergence near storm top were used to deduce updraft evolution within the storms. Dual-Doppler radar observations from a ground-based radar and an airborne Doppler radar provided fragmentary documentation of the storms' life cycles. The splitting storms on that day were unusual in two distinct ways: (a) the left members of the splitting storms were the dominant and longer-lasting ones, and (b) none of the deduced updrafts were collocated with centers of vorticity signatures that would have indicated updraft rotation. Both of the left-moving storms had 10 sequential primary updrafts, whereas their right-hand counterparts had 3 or 4 primary updrafts. Initial formation of the right-flank updrafts lagged behind the initial formation of the left-flank updrafts by 40-70 min. All the individual updraft summits moved in the general direction of the mean wind. Sequential updraft development on the left and right flanks of the storms suggested that expanding gust fronts provided the propagational component of storm motion.

Analysis revealed that the anchovies contained up to 485 ppm domoic acid in their viscera. This was the first reported incidence of domoic acid-related mortality of any organism in the United States. After this reported outbreak we obtained frozen samples of anchovies that were harvested near Newport, CA, in April 1991 and found they contained 270 ppm domoic acid in their viscera. By May, average domoic acid levels in frozen anchovy samples from this same area were less than 1 ppm. In October 1991, domoic acid was detected in razor clams (Siliqua patula) from Oregon and Washington and appeared to peak (an average of 106 ppm for all Washington State beaches) in the first week of December 1991. The averages then declined to less than 20 ppm without 6 months. However, domoic acid was still present at low levels (averages <5 ppm) in razor clams from Washington state beaches in December 1993. Dungeness crab (Cancer magister) in Washington and Oregon were also found to contain domoic acid, but only in their viscera. Domoic acid concentrations in the raw viscera of individual crabs from Washington state in December 1991 averaged 13 ppm and ranged from 0.8 to 90 ppm. The highest average levels of domoic acid in Washington state crabs were in the Grays Harbor and Willapa Bay samples, 32 and 31 ppm, respectively. By 1992 domoic acid level averages were <5 ppm in preseason samples of Dungeness crab taken along the Oregon and Washington coasts, ranging from 0 to 71 ppm. The highest levels of domoic acid in 1992 (36-71 ppm) were recorded in samples taken early in that year (January through April).

The vertical datum to which these limits are referenced must be adjusted every 25 to 30 years due to differential isostatic rebound. Because crustal movement unequally changes the land-to-water relationship along Lake Superior's shoreline, the method by which the limits are established on a new datum could accelerate the natural effects of crustal movement with adverse effects on shoreline flood levels, navigation depths, and lake outflows. With the implementation of the new International Great Lakes Datum of 1985, a study was undertaken 1) to review the methods used to establish the limits on previous datums and 2) to quantify the changed land-to-water relationship between the limits established in 1902 and those referenced to the new datum.

An approach which estimates the extent the artificial reef functions as an aggregator of biomass is proposed, based on habitat and ecological relationships. Applications of this approach indicate that new production due to the artificial reef may be in the range of 0.02-0.5 kg/m super(3) while catches at artificial reefs can be in the range 5-20 kg/m super(3). Hence, in these examples, artificial reefs serve primarily to aggregate fishes.

Growth was estimated from weight-converted length increments of 142 Floy-tagged individuals at liberty for a median of 187 days. Egg production was estimated for females of three taxa (four species) as the product of the weight of batch egg production and spawning frequency (the latter determined from histological evidence of day-old postovulatory follicles). Milt production was deduced from male to female ratios of gonad weights for reproductive fish. Somatic growth rates varied three- to fourfold among the six species and, in part, reflected the distribution of maturity stages of intraspecific populations. On average, the per capita growth rates of taxa dominated by immature stages were faster than those dominated by large adults. Somatic production varied more than somatic growth rates (by a factor of 15), because of additional variations in standing stock biomass among populations. The somatic production of at least one species was underestimated as a result of a tag effect on growth. Weight-specific egg production varied only twofold among the three taxa examined, perhaps because fishes with smaller batch egg productions compensated by spawning more frequently, and vice versa. Estimates of weight-specific milt production further diverged because of the influence of relative testis-to-ovary weights that ranged from a small fraction to unity. Additional variation among taxa in total gonadal (egg plus milt) production was about one-half that of somatic production (a factor of eight). Besides representing interspecific differences in adult biomass, variations in gonadal production reflected intraspecific differences in the biomass contributions of the two sexes within the fraction of adults that were reproductively active. Despite likely substantial underestimates of gametic materials, gonadal production ranged from a large fraction to a large multiple of somatic production among the four species. Our observations suggest that the elaboration of tissue unrelated to yield is nontrivial and represents a major component of energy flow through the fishes in this reef system and perhaps others.

Three species of juvenile Alaskan flatfishes: rock sole (Pleuronectes bilineatus), yellowfin sole (P. asper), and Pacific halibut (Hippoglossus stenolepis) were tested in laboratory chambers containing contaminated mud or sand offered in combination with clean mud, sand or granule. The flatfishes were able to detect and avoid heavily oiled (2%) sediment, but they did not avoid lower concentrations of oiled sediment (0.05%). Oiled sediment was favoured over unoiled sediment if the unoiled sediment was of the grain size not preferred by that species. Oiled sand or mud was always preferred over unoiled granule. The observed lack of avoidance at concentrations likely to occur in the environment may lead to long-term exposure to contaminated sediment following a spill. Recruitment of juveniles may be affected if the exposure to oil is long enough to affect growth and survival.

AN - 16719946; 3704893 AB - Fifty standard concrete modules were deployed on a sand bottom to make 16 replicated artificial reefs of 1 to 8 modules/reef. Fish assemblages were monitored for species composition, abundance, and fish size, and compared to two natural control sites. We censused 127 species (107, 168 fishes) from artificial reefs, 93 species (16,495 fishes) on natural control reefs, and 17 species (1,040 fishes) on sand bottom from July 1987 to March 1989. Artificial reefs supported a diverse, abundant, and dynamic assemblage of fishes that were a mixture of species found in surrounding sand and natural reef habitats. Colonization (number of species, individuals, and biomass) was very rapid. Abundance varied seasonally with recruitment episodes tending to occur in the spring and summer followed by losses for the remainder of the year. Assemblages were quite variable on and between similar sized reefs. Fish and biomass densities were higher at artificial reefs than on sand and natural reefs. Resident fish biomass varied less than resident fish numbers, because individual growth compensated for mortality after recruitment episodes. Reef size significantly influenced total numbers of species, individuals, and biomass. Smaller reefs had greater fish density while larger reefs had higher biomass density from larger, but fewer, individuals. Multiple small reefs supported more individuals and more species than one large reef of equal material. Fishes recruited by larval settlement accounted for 36% of the total resident abundance but only 2% of total biomass. As reef size increased, older juvenile or adult colonists comprised a greater percentage of total biomass (94% to 99%). Assemblage importance percentages (based on abundance, biomass, and frequency) were divided between residents (64%), visitors (20%), and transients (16%). Economically important species comprised 61% of the biomass and 55% of the individuals, among which settlers accounted for 94.3% of individuals but only 5.7% of their total biomass. The most highly valued species were visitors or residents that utilized the reefs after first settling elsewhere. These results showed that data on artificial reef assemblages based solely on the abundance of resident species are biased. Data on visitors, transients, frequency-of-occurrence, and biomass are important in evaluating bias. Results provided a partial test and support for a model predicting the importance of attraction over production for artificial reefs located in areas with high reef availability.

Visual assessments of fish assemblages were conducted in 1989 and 1990 in Onslow Bay, North Carolina, to quantify pelagic and demersal fishes associated with a natural rock outcrop and two experimental treatments of artificial habitats. The vertical relief component of both experimental habitats was held constant, resulting in an experimental design which allowed for a test of the effects of structural volume and complexity on fish abundance and pelagic prey/predator interactions. Experimental habitats were deployed 60 m perpendicular to a natural rock ledge in 25.5 m of seawater and floated 3 m off the bottom. Data supported the hypothesis that fish abundance is directly proportional to structural volume and complexity. Species richness and assemblage similarity indices indicated that experimental habitats deployed 3 m off the substrate and in close proximity to one another aggregated similar fish species regardless of structural volume and complexity. Analyses of pelagic fish abundance data suggested inverse relationships between predator and prey abundance. As shelter availability decreased, pelagic baitfish abundances decreased and predator abundances increased.

The consistent methodologies used to develop and compile the data enables comparative assessments across the Nation's estuaries. The NEI currently includes national data sets describing the physical, hydrologic, and natural resource characteristics for 106 estuaries of the contiguous United States. This paper provides an overview of the NEI, defining its importance, uses, and future vision. Although the knowledge available to effectively conserve and manage the Nation's estuarine resource base is limited, the NEI and associated data bases provide an important tool for assessing, comparing, and contrasting the biological and physical characteristics of the Nation's estuaries.

Significant and fundamental changes are required in how science, management, and public policy are conducted if the Nation is to effectively address its estuarine and coastal crisis with the limited resources available. Although many agree that the Nation's coastal resources and environmental quality are suffering, few have been able to accurately diagnose the causes and recommend possible cures. This paper identifies and describes several key aspects of today's changing decisionmaking context, offers a number of prescriptive and hopefully provocative observations and solutions, and summarizes briefly how several programs and activities of NOAA's Strategic Environmental Assessment Program continue to evolve as they provide information for decisionmaking in this changing context.

The NECOP study was initiated by the Coastal Ocean Program of the National Oceanic and Atmospheric Administration (NOAA) in 1989 to address the effects of nutrient discharge in the coastal waters of the United States. The basic hypothesis posed for NECOP is that the addition of anthropogenic nutrients from sewage, agriculture, industrial sources, and suburban runoff have contributed to the development of eutrophication in coastal waters with significant impacts on water quality. The coastal waters of the northern Gulf of Mexico were selected as the initial study site for NECOP based on a set of criteria developed by NOAA scientists and their academic colleagues. The criteria for the location of study include: A clear anthropogenic signal; a resultant nutrient-enhanced productivity of significant magnitude; a demonstrable impact of enhanced production on coastal environmental quality, and renewable resources of significant value.

Such multi-ridge-segment surveys of venting are accomplished most efficiently by mapping the distribution and intensity of hydrothermal plumes. In November 1991, we mapped hydrothermal temperature ( Delta theta ) and light attenuation ( Delta c) anomalies above the East Pacific Rise (EPR) continuously from 8 degree 40' to 11 degree 50'N, a fast spreading ridge crest portion bisected by the Clipperton Transform Fault. Plume distributions show a precise correlation with the distribution of active vents where video coverage of the axial caldera is exhaustive (9 degree 09'-54'N). Elsewhere in the study area the sketchy knowledge of vent locations gleaned from scattered camera tows predicts only poorly the large-scale hydrothermal pattern revealed by our plume studies. Plumes were most intense between 9 degree 42' and 9 degree 54'N, directly over a March/April, 1991, seafloor eruption. These plumes had exceptionally high Delta c/ Delta theta ratios compared to the rest of the study area; we suggest that the phase-separated gas-rich vent fluids discharging here fertilize an abundant population of bacteria. Hydrothermal plume distributions define three categories: intense and continuous (8 degree 48'-8 degree 58'N, 9 degree 29'-10 degree 01'N and 11 degree 05'-11 degree 27'N), weak and discontinuous (8 degree 58'-9 degree 29'N) and negligible. The location of each category is virtually congruent with areas that are, respectively, magmatically robust, magmatically weak and magmatically starved, as inferred from previous measurements of axial bathymetric undulations, cross-axis inflation and magma chamber depth and continuity. This congruency implies a fine-scale spatial and temporal connection between magmatic fluctuations and hydrothermal venting. We thus speculate that, at least along this fast spreading section of the EPR, cyclic replenishment, eruption and freezing of the thin axial melt lens exerts greater control over hydrothermal venting than the more enduring zones of crystal mush and hot rock. We found intense, and continuous, plumes along 33% of the surveyed ridge crest, an observation implying that any point on the ridge is, on average, hydrothermally active one-third of the time. Combining this result with the 20% plume coverage found along the medium-rate Juan de Fuca Ridge suggests that superfast ( similar to 150 mm/yr) spreading ridges should support vigorous venting along similar to 50% of their length, if spreading rate and along-axis plume coverage are linearly related.

The capability to adequately respond to an oil spill in Alaska can be hampered by a number of critical factors, which combined with the potential to experience large spills, require tools," other than mechanical response such as in-situ burning (ISB), be preplanned and immediately available to responders and government officials to ensure an adequate response to spill events. Because of this, the Alaska Regional Response Team (ARRT) has been working over the past 2 to 3 years to develop procedures and guidelines, scientifically based, to facilitate the decision process regarding ISB. The first major hurdle was developing a consensus that, outside the immediate region of the fire, the potentially most damaging effects of the smoke plume were those on the health and safety of the general population. The natural resource agencies were unable to document any adverse effects of the smoke plume on biological populations and/or habitats. The second hurdle occurred with the determination that particulates in the smoke plume less than 10 microns in diameter were the major culprit causing potential adverse effects to the general population. As a result, the Alaska Hazardous Substances Spill Technology Review Council funded the National Institute of Standards and Technology (NIST) to model downwind particulate concentrations for the burning of North Slope and Cook Inlet crude oils under typical winter and summer conditions in southern and northern Alaska. Based on a very conservative interpretation of the National Ambient Air Quality Standards (NAAQS), a particulate level of 150 micrograms per cubic meter ( mu g/m super(3)) - real time, one hour average - was selected as the acceptable exposure level to the general population. Using these parameters, the Alaska ISB guidelines now allow the Unified Command (FOSC and SOSC) to authorize ISB without RRT consultation. Provisions have been developed to conduct a trial burn, conduct controlled and uncontrolled burns, extinguish a burn, monitor a burn, and notify the public of a burn.

These collaborative efforts may be the greatest contribution that the sanctuary program can bring to the area of ocean management. Currently the oceans are managed resource by resource with little regard given to an integrated view of ecosystems. The interdisciplinary approach of these cooperative agreements may be a necessary first step toward a more comprehensive policy of ocean management.

The industry now produces approximately 100 000 mt of feed per year, up from less than 8000 mt 6 or 7 years ago. The number of feed producers has increased from several to 22 during this period. The quality of Chilean salmon feed has improved greatly in the last few years as well, advancing from the North American technology and formulations used in the early 1970s to produce moist feeds and pelleted salmon feeds to the industry's current level of quality, where the best feed producers manufacture feeds equivalent to the best salmon feeds produced in Europe and North America. In making these advances, the Chilean industry has not simply copied European and North American technology, but rather taken the best elements of foreign fish feed manufacturing and adapted them to Chilean needs. Both pelleted and extruded feeds are being produced for coho salmon, Atlantic salmon, and rainbow trout. The advantages normally associated with extruded feeds, such as higher lipid content and a slowly sinking pellet, are not critical concerns in the Chilean salmon industry. The range of feed ingredients available to the Chilean feed industry is lower than in Europe and North America, which limits the number of possible feed formulations in Chilean salmonid feeds. Thus, the quality of feed ingredients, particularly fish meal, and the quality of manufacturing are more important determinants of feed quality than is feed formulation. Future needs for the Chilean fish feed industry include less expensive and more efficient methods of pigmentation, a better understanding of the effects of biogenic amines on fish growth and product quality, and development of feeds that are less costly per kilogram of product sold. In the future, development of low-polluting feeds may also be desirable. JF - Aquaculture AU - Hardy, R W AU - Castro, E C AD - U.S. Dep. Commerce, NOAA, Northwest Fish. Sci. Cent., Utilization Res.

Environmental contamination is known to affect many aspects of lobster biology. Heavy metals, pesticides, pulp mill effluent, petroleum hydrocarbons and other pollutants can adversely affect lobster physiology and behavior. Sublethal concentrations of contaminants can stress lobsters, making them more susceptible to disease or other conditions that would normally be tolerated. Lobster embryos and larvae, particularly the first-stage, are sensitive to a variety of organic and metal pollutants. Sediments in New Bedford Harbor, Massachusetts, are heavily contaminated with polychlorinated biphenyls (PCBs); edible tissues of lobsters collected there have been found to contain PCB concentrations exceeding the FDA action level of 2 mu g/g wet wt. PCBs are strongly lipophilic and accumulate in fatty tissues including egg masses. Metals and PCBs are contaminants of concern in Long Island Sound. This study examines whether field exposure of ovigerous female lobsters to PCBs results in subsequent contamination of embryos, first-stage larvae, postlarvae, and juvenile offspring of "berried" lobsters from New Bedford Harbor and selected locations in Long Island Sound. Metal contamination in the embryos and offspring of Long Island Sound lobsters was also measured.

Gravimetrically estimated fecundities were compared in 1985-1991 between California, the southern extent of the species' distribution, and coastal waters of Washington, near the center of the species' abundance, where yellowtail rockfish are most heavily fished. California yellowtail rockfish were older, smaller in weight and length, and had smaller mesenteric fat deposits and more extensive disease and parasite pathologies than Washington fish. Egg production of this comparatively fecund viviparous fish increased linearly and sigmoidally with body weight and length, and asymptotically with age. Significant interannual differences were found in fecundities of young fish (age 14) or in young or old Washington fish. Washington yellowtail rockfish had higher group fecundities because they were larger at age. Rate-specific fecundities were significantly higher in young Washington fish. Predictive models of fecundity were highly correlated for young yellowtail rockfish, less so for old fish. Although fecundity of young fish depended on weight, length, and age, that of old fish was age-independent. Our findings show age-dependent interannual and geographic differences in reproductive effort, which suggest population-specific reproductive life histories.

Left sagittal otoliths from these fish were embedded in epoxy resin, and transverse sections through the foci were prepared. With hyaline zones considered as annual increments, ages ranged from 1 to 11 for 608 winter flounder; 97% of the fish were younger than age 5. The dorsoventral otolith diameter was determined by linear regression analyses to be the best (r super(2) = 0.90) of six "radial" axes for increment measurements. Marginal increment analyses for ages 1-4 showed that the increments, each composed of one opaque and one hyaline zone, are deposited annually, which clearly verified sectioned otolith ages for age-2 and age-3 fish. Opaque edges were prevalent in May, June, and July. Sectioned otoliths from winter flounder can provide clear increments and measurable increment widths through age 11. Two individuals read 369 sectioned otoliths and 116 whole otoliths; one individual read 155 scales twice. Precision between readers and aging methods was relatively high (average percent error, 1.5-4.5).

Aerosol samples were also collected on board research ships in four cruises over the East China Sea and Western Pacific Ocean to determine BC distribution. The data were used to verify a simple one-dimensional transport model. In the marine boundary layer with prevailing westerlies of 5 m/s, the BC total deposition rate, including both dry deposition and wet deposition, was computed as -1 x 10 super(-5)/s, and the half-life was estimated to be 19 h. The residence time was approximately 5 d, concentrations subsequently diminishing to the background level. Longer lifetime and farther transport would be probable in the free troposphere. Because BC particles have great surface areas and are very absorbent of electromagnetic waves, their concentration and distribution in the atmosphere may have profound effects on radiation budgets and climate change.

ER - TY - JOUR T1 - A multiseason climate forecast system at the National Meteorological Center AN - 16704212; 3635946 AB - Coupled Model Project was established at the National Meteorological Center (NMC) in January 1991 to develop a multiseason forecast system based on coupled ocean-atmosphere general circulation models. This provided a focus to combine expertise in near real-time ocean modeling and analyses situated in the Climate Analysis Center (CAC) with expertise in atmospheric modeling and data assimilation in the Development Division. Since the inception of the project, considerable progress has been made toward establishing a coupled forecast system. A T40 version of NMC's operational global medium-range forecast model (MRF) has been modified so as to have improved response to boundary forcing from the Tropics. An ocean reanalysis has been performed for the Pacific basin starting from July 1982 to present and uses a dynamical model-based assimilation system. This also provides the ocean initial conditions for coupled forecast experiments. The current coupled forecast model consists of an active Pacific Ocean model coupled to the T40 version of the NMC's MRF.

A forecast of future recruitment was made based on projected sea levels (Polovina and Mitchum, 1992). This note updates that forecast with two more years of data. These results provide some additional support to our original hypothesis that a positive relationship exists between the strength of the Subtropical Countercurrent and local larval survival, retention, and recruitment to the fishery at Maro Reef (Polovina and Mitchum, 1992).

The climatic change resulted in increased mixed layer depth and the frequency of deep mixing events, particularly during Jan-Mar. A number of biological time series for species ranging from primary to apex levels in the North-western Hawaiian Islands, show corresponding declines in productivity of 30-50% from the early 1980s to the present. We hypothesize that during the early 1980s, increased mixing due to the climate event resulted in greater nutrient input into the euphotic zone and ultimately increased ecosystem productivity. Productivity over a range of trophic levels declined when the climate event ended.

Recently, large numbers of this species were taken incidentally during research surveys conducted at Southeast Hancock Seamount in the central North Pacific Ocean. The information collected during 1985 to 1988 from these surveys is used to describe the life history, depth distribution, and biology of S. mitsukurii. Bathymetric distributional patterns of female and male S. mitsukurii differed slightly, although bottom longline catches revealed a depth distribution extending from the summit (260 m) to 740 m for both sexes. Males generally were found deeper than females. In addition, the size of males generally increased with depth whereas no apparent trend was observed for females. Reproductive parameters for both sexes are presented. Males tended to reach maturity at smaller sizes than did females. Gravid females had broods of up to six uterine embryos. Length of young close to parturition was 21-26 cm. Tentative estimates of age and growth were made from dorsal spine increment counts. Maximum ages were 27 years for females and 18 years for males. Females exhibited more rapid growth than males after about age 9. The diet of S. mitsukurii included both benthic and mesopelagic prey. Fishes, cephalopods, and crustaceans were the major components of the diet. Comparison of the biological characteristics suggest that this species is probably typical of other slow-growing, low fecund members of the genus Squalus. The 50% decline in catch rates observed during this study suggests that the number of S. mitsukurii on the seamount declined dramatically, possibly as a result of overfishing.

It is now recognized that eggs and larvae present a wide array of characters suitable for systematic analysis that are largely independent of adult characters. Fisheries recruitment studies focus on survival of eggs and larvae as the most important factor influencing variations in population abundance. A requisite to these studies is detailed information on the appearance of fish eggs and larvae in order to identify them in plankton samples. This paper reviews the proportions of fish species for which at least illustrations of eggs and larvae, sufficient to permit their identification in plankton samples, have been published worldwide and by geographic region. Factors which may influence differences in proportion of identifiable eggs and larvae by region are discussed. Factors considered important include species diversity, a history of important commercial fisheries, research emphasis, and interests of individual scientists in various regions. We conclude that although eggs and larvae of most species can now be identified in some regions of the world, there are still gaps in our knowledge that prevent realizing the full potential of ichthyoplankton studies in systematic and fisheries research. Filling these gaps will require continued traditional morphological research as well as application of biochemical genetic and rearing techniques.

Numbers of species and overall densities were highest on ledge habitat, intermediate on live-bottom (three categories of low relief [<15 cm] rock outcroppings covered by algae and macrofauna), and lowest over sand. On average, abundance over ledges exceeded that over sand bottoms by a factor of 50. Generally, community composition at sites over ledges and dense live-bottom areas was similar and distinct from sites found over sparse live-bottom and sand. Many species were found in more than one habitat and few individual species could be considered indicators of a single habitat type. A nondestructive, repeatable procedure of randomly dispersed video transects was devised for assessing diurnally active fishes.

NOAA has the responsibility for maintaining this valuable data resource; for improving, wherever possible, the quality of this resource; and for facilitating access to this resource by the entire Nation. To these ends, NOAA has undertaken to modernize its environmental data and information management system through an evolutionary process of development and implementation.

Based on a re-examination of the data gathering process, the system addresses the data collection needs at two shipboard sites: 1) the bridge where station location, date, time, and environmental parameters are recorded, and 2) the deck where species' identification, lengths, and net conditions are entered. The system developed under Pen-Pal for the PenRight operating system was loaded on a Fujitsu PoquetPad Plus unit (1.6 pounds) and the 325-Point unit (3.0 pounds). The software relies on lists, "buttons", and handwriting recognition to compile station and catch data at sea. The system offers the potential of performing routine audits of the data while at sea rather than after the completion of a cruise. The system was tested during the 1993 and 1994 NMFS scallop surveys in which stations were sampled from Cape Hatteras, NC to Georges Bank. When comparing the manual method to the pen-based method, reductions were noted in the type and quantity of errors encountered as well as the earlier availability of the data onboard the vessel. The time required to generate and report results from a cruise was markedly reduced.

Retention of congeneric females by the two samplers varied among months because of change in body size, species composition and abundance. This variability created bias in total daily egg production estimates when relying on female length and concentration from only one of the samplers.

The program works to gain a fundamental understanding of the physical and biological processes that control variations in abundance of marine animal populations and to partition the variance in abundance between natural and anthropogenic causes. The problem is attacked through a combination of modelling, process research, empirical studies, retrospective analysis and observations. We will be working in regions likely to be influenced by climate change - coastal ecosystems of the northwestern Atlantic (primarily Georges Bank), upwelling ecosystems of Eastern Boundary Currents (especially the California Current), and the Antarctic. The Georges Bank program is underway, with major field activities planned for Spring 1995. California Current work is now being planned and should see its first major field season in Spring 1997. The research involves participation between academic and NOAA physical and biological oceanographers, paleoceanographers, modelers and fishery biologists, and includes a strong commitment to funding academic investigators. In addition to U.S.GLOBEC activities, MER has initiated a modest program directed at the early detection of climate change. This program has begun with relationships between basin to global scale climate changes and recent, rapid declines in coral reef ecosystems, including increased frequency of coral reef bleaching.

Evidence from models and our long records of climate change strongly suggest a tie between the deep circulation cell of the Atlantic and climate change over Europe and North America. This circulation cell, nicknamed the "conveyor belt," brings heat northward from the tropics to the North Atlantic, warming northern Europe when its heat is released. Paleoclimate data suggest major climate change has occurred in the past when this "conveyor belt" slowed or stopped. ACCP has focused on analysis of the historical data, ocean-atmosphere modeling studies, and ocean observational activities designed to establish the variability of this north-south circulation.

Many climate system changes have periods longer than a few decades, making most instrumental records of past climate change too short to obtain this knowledge. Although many paleoclimatic time series exist, most records are limited to a few geographic regions, are not readily accessible, and often do not adequately resolve seasonal- to century-scale climatic variance. NOAA's Paleoclimatology Program is systematically filling this void by providing expertise and funding to: generate new paleoclimatic time series, synthesize these series with existing records, make these time series readily accessible, use paleoclimatic data to study natural climatic and the effects of altered climatic forcing, and test climate models by simulating past climates. This work is conducted in conjunction with the ICSU World Data Center (WDC) for Paleoclimatology, the IGBP PAGES (PAst Global changES) Core Project, and a strong group of external academic investigators. Through the World Data Center, paleoclimatic data are made available to the public over the Internet system through anonymous FTP and the development of the Paleo Vu browse and visualization tool. Several recent activities of the program have promoted development of climate records from the marine environment, including those from corals, eastern boundary current sediments and the development of database protocols for marine sediment samples.

Crabs were torpid at these low temperatures. Starfish, Asterias forbesi, were observed to prey on burrowed crabs. The proportion of crabs preyed upon increased as water temperatures declined through the winter, reaching up to 81% of crabs observed during a single dive. There was no significant difference in the size or sex of crabs preyed on by starfish and those which were not preyed upon. Starfish that were collected preying on crabs were not significantly different in size than those found on the surrounding bottom. Low temperature, which affect the physiology of normally motile megafauna, can greatly alter predator-prey dynamics.

The redeposition thicknesses that will cause significant faunal mortality in the deep sea are currently unknown. An experiment called the Benthic Impact Experiment (BIE) is being conducted by NOAA to address the effect of sediment redeposition. This experiment is being conducted in collaboration with Russian scientists from the Yuzhmorgeologiya Association aboard the R/V Yuzhmorgeologiya. In July 1993 NOAA initiated the BIE with baseline studies which included deployment of a transponder net and current meters, and side scan sonar / camera surveys in the study area. In August 1993 the baseline current meters were recovered, baseline box core samples were randomly collected from the study area, and sediment traps and current meters with transmissometers were deployed. Following the baseline activities the 4900-m deep experimental area was blanketed with varying thicknesses of sediment using the Deep Sea Sediment Resuspension System (D2). The D2 is designed to fluidize, lift and discharge a sediment slurry 5 m above the seafloor. In the BIE, the D2 was towed 49 times through a 150-m-x-3,000-m tow zone resuspending 4,000 mt of wet sediment. Northerly currents at the time of disturbance transported the bulk of resuspended sediment to the north as indicated by the sediment trap and transmissometer data. This data also indicates that the discharged sediment did not travel far, settling quickly as a sediment-laden fluid flow. After towing, additional box core samples were randomly collected in the area of heaviest resedimentation to determine the short-term impacts on macro- and meiofauna. In July 1994, further mapping of the deposition regime will be conducted using a multicore bottom sampler. Macro- and meiofauna samples will also be collected to monitor the effect of sediment redeposition one year later.

II: Prototype synthesis of the AVHRR-based vegetation index from terrestrial data AN - 16683936; 3696010 AB - Part I of this article reviewed an approach to modeling in scientific geographic information systems (GIS) by digitally synthesizing environmental parameters or phenomena as functions of other data. This interactive approach to global environmental modeling complements the approach of dynamic process models while enabling the scientist to rigorously assess the character of data used as boundary conditions in other models on widely available personal computers and workstations. Part II presents a case history using existing GISs to recreate the AVHRR-based vegetation index using data derived from in situ study on the Earth's surface. The example explores the relationship between the global vegetation index and ecosystems, soils, and precipitation, and defects in our present ability to describe these features. The degree of success of the model shows that GIS and the global change data base can be effective modeling tools, especially when functions are added to enhance the modeling capabilities of GIS.

The suggested approach is based on thresholding the AVHRR/Channel 4 (11 mu m) brightness temperature. The global space-time-angle dependent thresholds (monthly, 2 degree x 2 degree , for 30 degree -viewing angle bins) are estimated in two steps. First, a clear-sky background for Channel 4, in terms of means and standard deviations, is developed from GVI weekly composite data using their "greenest" subsamples. Second, this background is used to estimate the space-time-angle dependent thresholds. Both the size of the "greenest" subsample for deriving the climatology and its use for constructing the thresholds are discussed in detail using targets in central United States and Thailand. The approach is generalized further and applied globally. Special attention is devoted to the development of quantitative criteria to estimate the efficiency of both steps and to the improvement resulting from implementation of the proposed procedure of cloud screening.

This relationship is compared with the theoretical results described by Emanuel. The theoretical results are in agreement with the observations over a wide range of SST, provided that the tropopause temperature is assumed to be a function of SST. Each storm is examined to determine how close the observed intensity comes to the maximum possible intensity (MPI). Results show that only about 20% of Atlantic tropical cyclones reach 80% or more of their MPI at the time when they are the most intense. On average, storms reach about 55% of their MPI. Storms that are farther west and farther north tend to reach a larger fraction of their MPI. Storms are also more likely to reach a larger fraction of their MPI in August-November than in June-July. There is considerable interannual variability in the yearly average of the ratio of the observed maximum intensity to the MPI.

Our work examines Lumbriculus variegatus exposure to pyrene-dosed Lake Michigan sediment at 0.4 ng/g and 64, 132, 206, and 269 mu g/g. Both bioaccumulation and survival were followed to enhance Lumbriculus variegatus development as a bioassay organism. Lumbriculus variegatus accumulated sediment-associated pyrene rapidly and achieved apparent steady state within 48 to 168 h. The pyrene uptake clearances (k sub(s), g sed/g animal/h) ranged from 0.039 to 0.132 and decreased with increasing pyrene concentration. At high pyrene concentrations, the worms avoided the sediment, which reduced accumulation and likely minimized the mortality response. In addition, the effect of organism loading on bioaccumulation was determined at different animal densities, 1:10, 1:50, and 1:100 g dry weight Lumbriculus variegatus: g sediment organic carbon, and a sediment pyrene concentration of 0.4 ng/g. Surprisingly, the bioaccumulation declined as organism density decreased. Pyrene elimination was rapid in clean sediment (k sub(e) = 0.026 plus or minus 0.002/h) but was much slower in water (k sub(e) = 0.0043 plus or minus 0.0007/h). Bioavailability apparently declined for exposures in sediment stored 1.5 months, based on the estimate of k sub(e) from nonlinear regression compared to direct measures of elimination. The apparent decline was attributed to both a decline in lipid content during the experiment and changes in pyrene bioavailability. Finally, for bioaccumulation studies, gut purging at a set time (e.g., 24 h) may result in an underestimate of contaminant concentration in organisms. An elimination study with extrapolation to the initial body burden can ensure that biases due to incomplete elimination of gut contents and body burden losses during the purging process are minimized.

In Florida, we compared three planting methods (cores, stapled bare root, and peat-pot plugs) for shoot addition rate, coverage, and labor cost (harvest, fabrication, and deployment) using Halodule wrightii. Only planting methods and development rates were recorded for Syringodium filiforme. Fertilizer additions were made to peat-pot plantings of H. wrightii and Zostera marina in both North Carolina and Florida. Exclosure cages were tested to attempt to minimize bioturbation of H. wrightii and Z. marina in both North Carolina and Florida. Recovery from harvesting impacts to existing, natural beds of S. filiforme and H. wrightii were assessed in Florida. The peat-pot method was about 35% and 63% less expensive in work time than staples and core tubes, respectively. Response to fertilizer additions was masked by inconsistent release properties of the fertilizer, although some indication of positive response to phosphorus fertilizer in sediments with low carbonate content, and nitrogen in general, was detected. Complete loss of peat pots, largely ascribed to bioturbation, occurred in a large planting (Tampa Bay) but not in nearby smaller ones where exclosure cages were used. Cages did not affect planting unit survival in North Carolina but did improve number of shoots per planting unit in one of three experiments. No detrimental effects of cages were noted. Existing natural beds used to harvest transplanting stock in Tampa Bay recovered from excavations as large as 0.5 m super(2) in one year. Significant cost savings were found to be possible through methodological improvement, including planting techniques, bioturbation exclusion, and possibly fertilizer additions.

This same lesion has been recognized in a number of Pacific Coast marine fish species including starry flounder (Platichthys stellatus), rock sole (Lepidopsetta bilineata) and white croaker (Genyonemus lineatus), and our studies have shown that higher prevalences of this lesion occur in fish captured from highly contaminated sites. In starry flounder and white croaker, hydropic vacuolation is far more frequent than any other lesion type associated with contaminant exposure. However hydropic vacuolation has never been observed in English sole, which is a species considered to be particularly sensitive to toxicopathic liver disease on the basis of both field and laboratory studies. The morphology and ultrastructure of hydropic vacuolation is described in starry flounder, rock sole and white croaker, and compared with that of winter flounder. Relationships between presence of hydropic vacuolation, and contaminant concentrations in sediment and tissues of affected fish is discussed. JF - UNIV.

Prevalences of and relative risks for neoplastic, preneoplastic, nonneoplastic proliferative, unique degenerative/necrotic lesions, and hydropic vacuolation of cholangiocytes and hepatocytes were significantly higher in fish at contaminated sites in Puget Sound, the Los Angeles area, and San Francisco and San Diego Bays on the Pacific Coast, and in Boston Harbor and Raritan Bay on the Northeast Coast. In logistic regression analyses, exposure to polycyclic aromatic hydrocarbons (PAHs), PCBs, DDTs, chlordanes and dieldrin were significant risk factors for all lesions in Pacific Coast species. In winter flounder, exposure to PAHs, DDTs, or chlordanes were significant risk factors only for hydropic vacuolation, nonneoplastic proliferative and nonspecific necrotic lesions. Disease risk generally increased with fish age, but sex was rarely a risk factor. Although pathologic responses and chemical risk factors differed among species, these relationships provide strong evidence for environmental contaminants as etiologic agents for hepatic lesions in several marine bottomfish species, and clearly indicate the utility of these lesions as biomarkers of contaminant-induced effects in wild fish.

Whereas English sole develop hepatic neoplasms, the prevalences of which are strongly linked to exposure to polycyclic aromatic hydrocarbons (PAH), evidence of neoplasia is virtually nonexistent in starry flounder, even those residing in areas with very high levels of PAH in the sediments. Because PAH are activated to genotoxic forms by the action of cytochrome P450 1A (CYP1A) in teleosts, we are examining the hypothesis that variation in the hepatic expression of this major inducible cytochrome P450 isozyme may contribute to the differential contaminant response. These two species were captured in the Duwamish Waterway, a contaminated area of Puget Sound, Washington. Catalytic activity of CYP1A [determined as aryl hydrocarbon hydroxylase (AHH) activity] was measured in the liver to quantitatively assess the relative induction of CYP1A in these two species, and AHH activity was significantly higher in English sole than in starry flounder (p = 0.015). Cellular expression of CYP1A was determined by immunohistochemical localization of tissues, using an avidin-biotin peroxidase complex method, with polyclonal rabbit anti-cod CYP1A IgG. The results showed a markedly reduced expression of CYP1A in hepatocytes of starry flounder, which is consistent with the apparent resistance of this species to the development of hepatocellular neoplasia. This reduced expression of CYP1A in hepatocytes of contaminant exposed fish was previously seen in oyster toadfish from the Elizabeth River, VA, and this species is also apparently resistant to hepatocellular neoplasia.

(Cyanophyta) to the copepod Acartia tonsa AN - 16649469; 3685072 AB - The toxicity of the marine cyanobacterium Trichodesmium sp. to the copepod Acartia tonsa was assessed in a series of experiments during a Trichodesmium bloom off the North Carolina coast in late October 1992. Healthy intact cells of Trichodesmium sp. were not toxic to A. tonsa and were ingested by A. tonsa when no other foods were available. However, homogenized Trichodesmium cells were toxic to A. tonsa, suggesting that Trichodesmium sp. contains certain type(s) of intracellular biotoxins. This hypothesis was consistent with the observed high mortality when A. tonsa was treated with aging Trichodesmium sp. cells or with filtered cell homogenate. The affected copepods showed weakness, recumbency, and reduced responsiveness. Many were observed to have distended intestines. Bioassays using aged Trichodesmium sp. cell and filtered homogenate demonstrated a dose-dependent effect on A. tonsa survival.

It is composed of several productive and biologically diverse communities such as the coral reefs, seagrasses, and mangroves, some of which are showing signs of severe stress. Recognizing the threats to these unique resources, the President signed the Florida Keys National Marine Sanctuary and Protection Act (Keys Act) on November 16, 1990. The Keys Act calls for the protection of resources and requires NOAA to develop a comprehensive management plan. The sanctuary will be managed to allow continued, compatible multiple uses while achieving the resource protection goals of the Keys Act. This will be accomplished through coordinated inter/intra agency resource protection efforts, education which promotes wise-use of resources, zoning to minimize conflicts and protect biodiversity, and research designed to better understand the ecosystem. In addition to identifying research needs, the Keys Act requires that NOAA establish a long-term ecological monitoring program. To successfully protect this ecosystem, NOAA must understand and monitor its health. This will require considerable input from researchers. This paper will review research needs and will propose a framework for a long-term monitoring program for the sanctuary.

Shallow Banks AN - 16648370; 3654055 AB - Drop sampling in 1990-92 compared fishes and decapods in healthy Thalassia, open water caused by die-off, and algal and Halodule regrowth. In waters less than or equal to 1 m depth, fishes were dominated by Lucania in Thalassia and by Floridichthys elsewhere. Decapods were dominated by Thor in Thalassia and by a mixture of Thor, Penaeus and Pagurus elsewhere. Fish and decapod densities were usually highest in Thalassia, lowest in open water, and intermediate in Halodule and algae. Fish and decapod species diversities were usually higher in disturbed habitats. These distributions may be affected by behavior, feeding or predation. Laboratory experiments with Lucania and Cyprinodon (a congener of Floridichthys) indicated that single species distributions may be altered when schools of different species interact. Infaunal communities were altered as well. Predatory Opsanus consumed more Lucania in disturbed habitats than in healthy Thalassia.

A microextraction technique was developed which utilizes 100 mu L of total extraction volume and as few as 20 copepods (approximately 25 mu g of dry tissue mass). Copepods were homogenized and extracted in a 100- mu L closed vial with alkaline media (4 M NaOH, 50 mu L) and isooctane (50 mu L) spiked with an internal standard (hexachlorobenzene), creating a colloidal suspension. After centrifugation, Aroclor 1254 quantification by GC-ECD was directly determined from the organic solvent phase. Spiked samples of Aroclor 1254 yielded recoveries of 95% plus or minus 12% (n = 11). Body burdens of sediment exposed (88.3 plus or minus 6.6 ng/mg of dry weight sediment) copepods were measured over a 12-day period, and predicted body burdens with 95% confidence intervals were calculated. Maximum levels found in A. tenuiremis (0.39 ng/ mu g of dry tissue weight) and M. littorale (0.23 ng/ mu g of dry tissue weight) were reached after 8 days of exposure and agree with other uptake values reported in the literature. This technique allows for the quantification of total PCBs in very small sample masses (approximately 25 mu g of dry tissue weight).

Lesions detected were neoplasms, preneoplastic foci of cellular alteration, nonneoplastic proliferative lesions, unique or specific degenerative/necrotic lesions, nonspecific degenerative/necrotic lesions, and hydropic vacuolation of biliary epithelial cells and hepatocytes. In general, lesion prevalences were significantly higher in all three species captured at chemically contaminated urban sites, and certain lesions had significantly higher relative risks of occurrence at urban sites in Puget Sound, San Francisco Bay, the vicinity of Los Angeles, and San Diego Bay.

Samples were examined for growth of L. monocytogenes and total aerobic microorganisms at specific intervals for up to 50 d. Sodium lactate exhibited a concentration-dependent antilisterial effect that was enhanced by nitrite and/or increased concentrations of NaCl. At 5 degree C, total inhibition of L. monocytogenes was achieved for up to 50 d by 2% sodium lactate in combination with 3% water-phase NaCl.

Particles were tracked in monthly-mean flow fields generated by a three-dimensional numerical circulation model in response to the M sub(2) tide, high and low Scotian Shelf inflows, and the 1982 and 1985 monthly-mean windstresses from February through May. Passive particles were released each year in the northeast Georges Bank spawning area on 1 February, 1 March, or 1 April and tracked until 1 June. The resulting Lagrangian description of the circulation was used to examine the effects of variable advection and spawning date on larval distributions for the two years. In all cases, significant numbers of particles remained on the Bank at the end of each month, suggesting that there is high potential for some larvae to remain on the Bank under a wide range of flow conditions.

Included in the suite of instruments were (1) the NOAA Environmental Technology Laboratory (ETL) three-channel microwave radiometer, (2) the NASA GSFC Raman lidar, (3) ETL radio acoustic sounding system (RASS), and (4) frequent, research-quality radiosondes. The Raman lidar operated only at night and the focus of this portion of the experiment concentrated on clear conditions. The lidar data, together with frequent radiosondes and measurements of temperature profiles (every 15 min) by RASS allowed profiles of temperature and absolute humidity to be estimated every minute. We compared 2-min measurements of brightness temperature (T sub(b)) with calculations of T sub(b) that were based on the Liebe and Layton (1987) and Liebe et al. (1993) microwave propagation models, as well as the Waters (1976) model. The comparisons showed the best agreement at 20.6 GHz with the Waters model, with the Liebe et al. (1993) model being best at 31.65 GHz. The results at 90 GHz gave about equal success with the Liebe and Layton (1987) and Liebe et al. (1993) models. Comparisons of precipitable water vapor derived independently from the two instruments also showed excellent agreement, even for averages as short as 2 min. The rms difference between Raman and radiometric determinations of precipitable water vapor was 0.03 cm which is roughly 2%. The experiments clearly demonstrate the potential of simultaneous operation of radiometers and Raman lidars for fundamental physical studies of water vapor. JF - Journal of Geophysical Research. D.

The analyses use 7 days of in situ (ship and buoy) and satellite SST. These analyses are produced weekly and daily using optimum interpolation (OI) on a 1 degree grid. The OI technique requires the specification of data and analysis error statistics. These statistics are derived and show that the SST rms data errors from ships are almost twice as large as the data errors from buoys or satellites. In addition, the average e-folding spatial error scales have been found to be 850 km in the zonal direction and 615 km in the meridional direction. The analysis also includes a preliminary step that corrects any satellite biases relative to the in situ data using Poisson's equation. The importance of this correction is demonstrated using recent data following the 1991 eruptions of Mt. Pinatubo. The OI analysis has been computed using the in situ and bias-corrected satellite data for the period 1985 to present. JF - Journal of Climate AU - Reynolds, R W AU - Smith, T M AD - Natl. Meteorol.

Pinatubo volcano had a major eruption that injected a considerable amount of dust, ash, and sulfur dioxide gas into the atmosphere. This volcanic cloud blocked the amount of energy reaching the Earth's surface causing, in turn, a decrease in NDVI values specifically in the tropics. Estimates have been made which showed changes in NDVI during pre- and post-Pinatubo periods. Two-three weeks after the Mt. Pinatubo eruption the NDVI started to decrease, progressing until fall 1991. After that period, a gradual recovery of NDVI was observed, resulting from a diminishing of aerosol optical thickness.

Densities of nekton were compared among canals and between shallow (<1 m) and deep ( greater than or equal to 1 m) areas within canals to test two null hypotheses: H sub(1): Densities of nekton in pipeline canals are not related to maximum canal depth and H sub(2): Densities of nekton in shallow and deep subtidal areas of canals are equal. Daggerblade grass shrimp Palaemonetes pugio, bay anchovy Anchoa mitchilli, blue crab Callinectes sapidus, brown shrimp Penaeus aztecus, and gulf menhaden Brevoortia patronus numerically dominated nekton assemblages in both brackish and saline canals. Naked goby Gobiosoma bosc, rainwater killifish Lucania parva, and gulf pipefish Syngnathus scovelli were dominant only in brackish canals, whereas white shrimp Penaeus setiferus and Atlantic croaker Micropogonias undulatus were abundant in saline canals only. Although variation in the abundance of most numerically dominant species could not be related to maximum canal depth, the distribution of several species within pipeline canals was influenced by habitat depth and other interrelated factors. The degree of habitat segregation with depth was largely influenced by submerged aquatic vegetation (SAV) and salinity as well as water depth. Habitat segregation with depth was most pronounced in brackish canals during late spring (May) when SAV was present. Naked goby, rainwater killifish, blue crabs, and daggerblade grass shrimp were significantly more abundant in shallow water (<1 m) at this time. In saline canals, most blue crabs and daggerblade grass shrimp occupied shallow habitats in March when small juveniles of these species reached peak abundance. Bay anchovy exhibited a pattern opposite that of other species. In March, bay anchovy abundance was positively related to maximum canal depth in brackish canals, and densities were greater in deep than shallow areas of saline canals in June. Salinity may have affected the distribution of freshwater species (e.g., centrarchids) and limited their occurrence in saline canals. Increasing shallow subtidal habitat by backfilling canals may enhance the nursery habitat for some species, especially in brackish canals where the area of subtidal habitat capable of supporting SAV would be expanded.

In offshore Lake Huron, where copepod nauplii were the only zooplankton, Bythotrephes cleared them at a relatively high rate (0.55 liter/d). These results were used to determine if Bythotrephes was responsible for recent changes in the cladoceran assemblage in Lake Michigan. Based on maximum abundance estimates, Bythotrephes induced a maximum mortality of 0.05/d. This modest predation rate and the high selectivities for most cladocerans suggest little impact; however, this estimate ignores possible spatial coupling between Bythotrephes and its prey.

An example of this problem concerns areas that produce poor environmental conditions for regeneration upon clearcutting. Valigura and Messina (1994) found that loblolly shelterwoods substantially influence the temperature, radiation, humidity and windspeed of the seedling-level microclimate relative to those in a clearcut, but they could not predict the effects of these modified understory conditions on seedling performance. The primary question addressed in this study is: on harsh sites, what advantages/disadvantages does a partial overstory impose on seedlings growing underneath relative to seedlings grown in a clearcut? The objective was to evaluate the combination equation for potential evaporation as a relative means to infer the amount of stress imposed on loblolly pine seedlings in a shelterwood or clearcut environment, subsequently inferring the effect of a partial overstory on seedling performance. It was shown that although PE statistically explained some of the variance measured in seedling physiological variables, it was not possible to use PE estimates to infer seedling performance to microclimate, on these sites, during the relatively wet period of 1990/1991. This study qualitatively confirmed the ability of a shelterwood to favorably influence the seedling microclimate relative to a clearcut microclimate. However, there is still a need to explore and develop an inferential technique to evaluate the effect of different environments on seedling performance.

The OLR is obtained from 4 yr of data from the Earth Radiation Budget Experiment (ERBE), while T sub(s), W, and RH are obtained from objective analyses of rawinsonde and ship data. It is found that in the midlatitudes, the surface temperature explains over 80% of the variability in the clear-sky OLR (F sub(cs)) and almost half of the variability in the total OLR (F sub(tot)). It fails badly in the tropics and subtropics, however, where T sub(s) explains only about 20% of the variability in F sub(cs), and is largely decoupled from F sub(tot). The two-dimensional contour plot of the OLR binned with respect to T sub(s) and RH is marked by distinct changes in the gradient that are consistent with inferences from earlier investigations. For low values of T sub(s) (<10 degree C), the OLR depends mainly on T sub(s). For values of T sub(s) above 10 degree C, the OLR depends increasingly on RH. Specifically, in the tropics (T sub(s) similar to 25 degree C), the total and clear-sky OLR depend significantly on both T sub(s) and RH. The well-known drop in OLR in the tropics with increasing T sub(s) correlates directly to an increase in RH, and not to changes in T sub(s). The authors suggest that the observed dependence of the OLR on T sub(s) and RH be a minimum performance standard for climate models. This approach is illustrated by comparing the observed dependence with the results of a radiative transfer model and an R15 general circulation model, and by discussing the strengths and limitations of using RH to parameterize the OLR.

However, virtual temperature is a function of atmospheric moisture content as well as temperature. This paper investigates the impact of real or apparent changes in atmospheric moisture on changes in mean layer virtual temperature. Real changes in mean layer specific humidity of up to 50% would cause changes in mean layer virtual temperature of less than 1 degree C, except in the tropical boundary layer, where the high moisture content would lead to larger virtual temperature changes. The effect of humidity changes is negligible in polar regions and most pronounced in the tropics, which could influence the interpretation of the latitudinal gradient of virtual temperature trend estimates. Improvements in radiosonde humidity sensors since 1958 have led to an apparent decrease in atmospheric humidity. On global average, for the 850-300-mb layer, such changes are estimated to contribute to an apparent cooling of between 0.05 degree and 0.1 degree C, or about 10% to 20% of the observed warming trend since 1958.

Recapture data from 373 tags recovered through the first quarter of 1992 revealed a strong seasonal component in fish movement between summer and winter areas. Prespawning fish were tagged throughout their summer distribution, primarily over the inner and middle shelf (100-200 m) and upper continental slope (>200 m) in subsequent quarters. Recoveries from the winter quarter (January-March) showed the most directed movement, when Pacific cod aggregated in major spawning areas between Unalaska and Unimak islands in the eastern Aleutian Islands, seaward of the Pribilof Islands along the shelf edge in the eastern Bering Sea, and near the Shumagin Islands in the western Gulf of Alaska. By early summer, a hypothesized postspawning dispersal was observed from these overwintering areas, when tagged Pacific cod moved from deep off-shelf waters to shallower depths on the eastern Bering Sea shelf. The importance of seasonal migration was examined statistically by contingency table analysis, which indicated that season of recovery affected area of recovery more than either the season or area of tagging. Seasonal movements were further quantified by modeling the population dynamics of tagged individuals, which allowed estimation of the seasonal distribution in the eastern Bering Sea population. These estimated seasonal distributions compare well with the seasonal distribution of catches from the commercial fisheries. This analysis of tag-recapture data suggests a single winter spawning population in the eastern Bering Sea, nearby waters of the Aleutian Islands, and western Gulf of Alaska waters between longitude 157 degree W and 170 degree W.

The walleye pollock allocation, which generated the most concern, would apportion specific shares of the allowable catch to each of the two harvesting sectors, inshore and offshore, along with a set-aside for Alaska community development. The potential transfer is of enormous economic value for industry participants and underscores the importance of identifying the net economic gains (or losses) to the nation that might arise under the proposed allocation scheme. For this reason, a benefit-cost analysis was pivotal in the allocation decisions reached by the U.S. Department of Commerce. The benefit-cost analysis of the allocation proposal served to focus attention on the need for consistent social welfare accounting, of the kind that benefit-cost analysis provides, when management actions are evaluated. Conceptual and practical problems associated with the analysis are discussed as well as their solutions, and fundamental concerns that may be peculiar to benefit-cost analysis in fisheries are specifically noted.

A previously known annual variation and near-background levels are present in the record. The data are of high accuracy, being primarily obtained from an automatic precision sunphotometer and reduced using the Langley-plot slope method. The tau sub(a) values over Mauna Loa were greater immediately after the eruption of El Chichon than after Mount Pinatubo due to more direct transport from El Chichon. However, Pinatubo had a greater temporally integrated impact because of greater erupted sulfur mass. A mean solar irradiance decrease of 6.5 ( plus or minus 2.5) W m super(-2) per 0.1 tau sub(a) (500 nm) averaged over 24 hours is observed for both volcanic eruptions. Slight differences are suggested between the eruptions, but the differences are not statistically significant.

We conducted these experiments from June through Sep in an artificial stream with recirculating water and used a replicated, completely randomized design. The experiment was initiated with four allopatric treatments of 14 brown trout each and four sympatric treatments of 7 brown trout and 7 steelhead each. Mortality during the experiment resulted in variable densities among replicates. Interactions with steelhead did not have negative effects on brown trout survival or growth. A model comparing the effects of total salmonine, steelhead, and brown trout densities on brown trout length suggested that intraspecific interactions had the strongest influence. Our results indicate that the steelhead did not influence the brown trout survival or growth during the summer growth period to the same extent as an equivalent number of brown trout. However, we recommend caution in combining these two species until the implications of interactions at other life history stages are examined.

Now, the nature of environmental degradation is usually different. We are faced with pollutants and effects with more subtle cause effect relationships, often characterized by larger geographic areas of interest and longer term potential damage; the potential risk is now more chronic than acute. Acid rain and climate change are good examples, in that they are associated with a variety of pollutants from a number of sources and damage to ecosystems occurs over many years. It is argued that monitoring programs should evolve to reflect the changing nature of the environmental problems they are addressing. It is now necessary to consider interactions among many pollutants, mixing among the various media, and potentially affecting many components of the ecosystem in both indirect and direct ways. Here, integrated monitoring and analysis is presented as a unifying strategy to bring together different measurement methodologies in different disciplines, addressing environmental questions of complexity beyond the scope of many existing activities that have a classical narrower focus. The underlying concept is of nested networks, each tier being composed of sites selected for specific purposes but arranged to maximize the number of common sites where more multidisciplinary questions can be addressed.

These processes are decoupled in tunas by the presence of vascular counter-current heat exchangers, and sustained (i.e., steady state) muscle temperatures may exceed water temperature by 10 degree C or more in larger individuals. The presence of vascular counter-current heat exchangers is not clearly advantageous in all situations, however. Mathematical models predict that tunas could overheat during strenuous activity unless the efficacy of vascular heat exchangers can be reduced, and that they may be activity limited in warmer waters. Tunas may likewise be forced out of potentially usable habitats as they grow because they have to occupy cooler waters. Vascular counter-current heat exchangers also slow rates of heating and cooling. A reduced rate of muscle temperature decrease is clearly advantageous when diving into colder water to chase prey or avoid predators. A reduced rate of heat gain from the environment would be disadvantageous, however, when fish return to the warmer surface waters. When subjected to changes in ambient temperature, tunas cannot defend a specific body temperature and do not thermoregulate in the mammalian sense. Yet when appropriately analyzed, data taken under steady state and non-steady state conditions indicate that tunas are not strictly prisoners of their own thermoconserving mechanisms. They apparently can modify overall efficiency of their vascular counter-current heat exchangers and thus avoid overheating during bouts of strenuous activity, retard cooling after diving into colder water, and rapidly warm their muscles after voluntarily entering warmer water. The exact physiological mechanisms employed remain to be elucidated. JF - Environmental Biology of Fishes AU - Brill, R W AU - Dewar, H AU - Graham, J B AD - Honolulu Lab. Southwest Fish. Sci.

Velocity and water property measurements AN - 16600450; 3662713 AB - In September 1988 six sections were occupied across the Mediterranean outflow plume in the Gulf of Cadiz within 100 km of the Strait of Gibraltar. Vertical profiles of temperature and salinity were collected at CTD stations. Velocity and temperature profiles were collected with expendable current profilers at a subset of these stations. At the channel base, the plume undergoes geostrophic adjustment and turns northwest to flow along the continental slope. There it decelerates and spreads gradually down the slope as friction slows the current and allows it to cross isobaths. Within the plume, downstream velocity and density increase rapidly in the interfacial layer with depth to the velocity maximum, or nose, 5-150 m above the bottom. Below the nose, in the bottom layer, downstream velocity decreases rapidly toward the bottom, but the stratification is weak. Ekman-like veering occurs in the interfacial layer. Local bottom stresses on the plume are estimated by fitting the near-bottom velocity profiles to a log-layer model. These stresses are compared with bulk estimates of total stresses from momentum budget residuals and of interfacial stresses from combining the mean vertical shear with bulk turbulent dissipation estimates. The downstream pattern of the sum of the local bottom stresses and the bulk interfacial stresses agrees well in magnitude and distribution with that of the bulk total stresses. The largest stresses reach a mean of 5 Pa where the plume is flowing rapidly westward down a channel after exiting the strait, thinning, and accelerating. These stresses are an order of magnitude larger than mean wind stress values over the ocean gyres and exceed most bottom stress estimates in other regions.

Much of this work has focused on deleterious effects in benthic species exposed to contaminated sediments. These effects include increased prevalences of toxicopathic hepatic lesions, elevated biliary levels of metabolites of aromatic hydrocarbons (AHs) and increased activities of hepatic xenobiotic metabolizing enzymes. Review of the data suggested that these effects were first exhibited at some threshold. Using Hockey Stick regression, a comprehensive analysis of these data was undertaken to estimate threshold AH concentrations in sediment for effects observed in English sole, winter flounder and white croaker. The Hockey Stick model assumes that organisms exhibit toxicopathic conditions only after detoxification and repair mechanisms have been overwhelmed, and thus is a two segmented regression composed of a line with zero slope representing a mean background response at low contaminant levels and a positive linear response at higher levels. Our results show that most effects exhibit thresholds at 500-1000 ng total AHs/g sediment (dry wt). For hepatic lesions these concentrations are substantially lower than those at which significant increases in lesion prevalences would be detected using multiple comparison techniques (e.g. as in determination of NOELs). This kind of analysis may serve as a useful tool for assessing differences in species sensitivity to toxicants and may provide significant insight into the impact of chronic exposure to low levels of contaminants on the health of aquatic organisms.

The parameterization captures the essential features of the convective and stable boundary layers and includes the effects of surface and volumetric sources of pollutants and trace gases. Initial tests are performed with a one-dimensional model. These tests show that the parameterization is mass conserving and gives realistic results. The volumetric source term can be used to model photochemical production of ozone in the convective PBL, and the surface source term can be used to model emissions such as radon or methane.

By October of 1991, domoic acid was found in razor clams (Siliqua patula) and in the viscera of Dungeness crab (Cancer magister) along the coasts of Washington and Oregon. In response to this outbreak, the National Marine Fisheries Service, in cooperation with the Washington State Department of Fisheries began analysis of Washington State razor clams for the period from November 1991 to June 1993. This survey indicated that domoic acid levels in the edible portion of the razor clams peaked in December of 1991 (average of all Washington state coastal sites: 106 ppm) and followed a slow decline to the present day low levels (<5 ppm). Sixteen months after the maximum level, domoic acid has not completely disappeared from the razor clams from the Washington State beaches. Unlike mussels (Mytilus edulis), where the toxin is found only in the viscera, domoic acid distributes itself throughout the various body parts of the razor clam. The highest concentration occurs in the foot or "digger" and the lowest in the siphon or "neck." The concentration of domoic acid in the razor clam foot reached a high of 230 ppm.

To determine probable effects of the flooding on juvenile salmonids (Oncorhynchus spp.), two rotary-screw traps were used to estimate smolt yield inside and outside the predicted flood zone. Traps were fished from April to mid-August 1990: one at the predicted upstream limit of flooding and the other 3 km upstream from the river mouth. Every week, a sample of each salmonid species was tattoo-marked and released 1 km above each trap; recaptures were used to expand catches to estimate smolt yield. Trap efficiency ranged widely among species, from 3% for steelhead (O. mykiss) to 24% for chinook salmon (O. tshawytscha). Estimated total smolt yields were 900,000 sockeye salmon (O. nerka), 213,000 coho salmon (O. kisutch), 67,000 chinook salmon, and 26,000 steelhead; only sockeye salmon (34% of this species' smolts) originated in the flood zone. Estimated mortality between traps was 8% for coho salmon, 13% for chinook salmon, and 16% for sockeye salmon. Our study demonstrated that upriver and downriver rotary-screw traps and mark-recapture techniques can partition smolt yield, but mortality between traps and mark recognition must be considered.

Although much smaller in size than many national marine sanctuaries in the United States, the reserves in France represent successful efforts to protect and manage coastal marine areas. This is due in part to a high amount of local involvement during the designation process; the use of advisory committees at the reserves as well as scientific committees, which develop and conduct research projects within the sites; and the use of core areas, in which almost all human activities are prohibited or restricted, to promote repopulation of fish communities and to increase species diversity. The initiative for creating the reserves begins at the local level and is coordinated among local officials, user groups, environmental organizations and the national government. This study describes the legal framework in which the reserves are created and examines aspects of management, scientific research, and law enforcement of a marine reserve.

In this paper, we present a modification to the selectivity equation used in an earlier approach which reduces heterogeneous error variance. Non-linear least-squares parameter estimates are used to estimate the population size composition corrected for the effects of mesh selectivity and a procedure is described to estimate their variances. We applied the selectivity model and variance estimation procedure to the experimental gillnet catches of spotted seatrout from 1988 to 1990 and examined model selection parameter estimates, corrected population size compositions, and their variances. Likelihood ratio tests indicated that model selection parameter estimates were significantly different between the sexes (P<0.01), suggesting that factors which affect the selection process may differ between the sexes. Corrected size compositions for female and male spotted seatrout population were found to differ substantially from the observed catch frequencies, indicating negative bias for smallest size classes. Variability associated with corrected size composition estimates, as expressed by 95% confidence intervals, indicated that in general, precision associated with those quantities is good.

From July 1989 to June 1990, we conducted aerial surveys in the oceanic north-central Gulf (long. 87.5 degree W-90.5 degree W) with the following objectives: 1) to determine which cetacean species were present; 2) to document temporal and spatial distribution for each species; and 3) to estimate relative abundance for each species. We surveyed a total of 20,593 transect km and sighted at least 18 species. Of 278 identified herds (6,084 animals), 94% of the herds and 98% of the animals represented seven species or species groups: Risso's dolphin, Grampus griseus (22% of the herds, 13% of the animals); sperm whale, Physeter macrocephalus (16%, 1%); bottlenose dolphin, Tursiops truncatus 14%, 7%); Atlantic spotted dolphin, Stenella frontalis (13%, 15%); pygmy sperm whale, Kogia breviceps, and dwarf sperm whale, Kogia simus (12%, 1%); striped dolphin, Stenella coeruleoalba, spinner dolphin, S. longirostris, and clymene dolphin, S. clymene (9%, 34%); and pantropical spotted dolphin, S. attenuata (8%, 27%). Each of these species or species groups was sighted throughout the area surveyed in at least three seasons. Mean water depths of bottlenose dolphin and Atlantic spotted dolphin sightings were less than 400 m; mean water depths of Risso's dolphins and pygmy and dwarf sperm whales were between 400-600 m; and mean water depths of striped, spinner, and clymene dolphins, sperm whales, and pantropical spotted dolphins were greater than 700 m. Mean herd sizes varied by species and species groups and ranged from 1.9 animals for pygmy and dwarf sperm whales to 87.8 animals for striped, spinner, and clymene dolphins.

Eighty replicate samples per data allowed precise estimates of the abundances of juvenile and adult stages of all macrofaunal taxa and many meiofaunal taxa. We describe the multivariate structure of the seasonal succession of this community with a faunal distance metric approach. There were three groups of species that produced a three-stage or triangular succession pattern. Stage 1 is defined by a March bloom of harpacticoid copepods that closely follows a benthic diatom bloom. Harpacticoid copepod abundance rapidly declines in late spring and is followed by the recruitment of four opportunistic annelids, marking the break between stages 1 and 2. Stage 2 is a dense assemblage of four surface-deposit feeding and shallow subsurface-deposit-feeding annelids that reach peak abundance in June and decline in late summer, marking the break between stages 2 and 3. Stage 3 populations are more diverse than stage 2, reach peak abundance in fall, and decline in late fall. The infaunal community structure of December resembles that of the community the previous January. Succession on this mudflat is a fast-paced and dynamic process affected by epipelic diatom production, the timing and duration of juvenile recruitment, and the ability of the infauna to survive in dense assemblages of tube builders.

Ten usable instrument records ranging from one month to one year in duration were obtained; eight of them near-bottom records. Seasonal and geographic variability of wind-induced flow were examined. The wind is most efficient in driving the subtidal currents in the 2-10 day frequency band during winter when the water column is well mixed and when the eastward component of the wind often induces and sustains an up-valley (northward) bottom flow.

The aggregation consisted primarily of oldshell, multiparous female crabs which formed mounds 1-2 m in diameter, 0.5-1.0 m high, and spaced at intervals of 1-2 m. Mounds contained hundreds of crabs each at densities > 10/m super(2). Male crabs were found mating with females at the periphery of the aggregation, with sex ratios (male to female) varying from 1:10 to 1:100. The entire aggregation covered an area of about 2.2 ha and included approximately 100 000 crabs. No mounds were observed in May 1992, but recently spawned female crabs were found buried in the sediment at high densities (up to 2.2/m super(2)) over an area of about 25 ha, suggesting that aggregation had reoccurred at the same location. Newly ovigerous females exhibited a cycle of nocturnal activity and diurnal burial whereas unmated crabs remained exposed on the sediment surface. Many body parts and presumably dead crabs were observed. We conclude that aggregative mating is a major mode of reproduction in the family Majidae.

The two-dimensional data sets have a spatial resolution of approximately 2.5 km and are geo-referenced with latitude and longitude. A lake bathymetry data set was also produced for the same grid. The objective of assembling these particular data sets was to develop a computer tool to visualize and explore spatial and particularly temporal relationships between long-term averages of temperature (surface and lake-averaged vertical profile), ice cover, and bathymetry on a given lake and between lakes. Here, we briefly describe the data sets, summarize data sources and algorithms used to develop these data sets, and discuss the limitations of these data. We also briefly summarize the capabilities of the interactive menu-driven system to manipulate and display the daily long-term average temperatures and ice cover.

Turbulent dissipation and shear measurements AN - 16579044; 3662714 AB - Bottom and interfacial stresses on the Mediterranean outflow plume are estimated using vertical profiles of turbulent dissipation and velocity collected in the Gulf of Cadiz. Turbulent dissipation is high throughout the plume, with a local minimum often present near the plume nose (depth of maximum downstream velocity). Bottom stresses are estimated by applying a log-layer model to the dissipation measurements. The dissipation measurements are also divided by plume-scale vertical shear from the horizontal velocity profiles to construct profiles of stress within the plume. The mean stress estimates in the bottom layer agree well with those calculated in the log layer from the dissipation measurements alone. The bottom-layer means are slightly larger than those of the interfacial layer. The maximum stresses in each layer are uncertain, since they depend on the ill-defined shape of the stress profiles within the plume. Dissipation-derived stress estimates in the log layer and those from dissipation measurements combined with the plume-scale vertical shear of horizontal velocity are roughly one-third the magnitude of those made in the log layer from velocity measurements and those made in the interfacial layer from the residuals of bulk mass and volume budgets (Part I). Possible reasons for this discrepancy are advanced. JF - Journal of Physical Oceanography AU - Johnson, G C AU - Lueck, R G AU - Sanford, T B AD - NOAA/Pac. Mar. Environ.

Most of the buoys were drogued at 40 m. A composite current pattern is derived using these data. The two principal currents (the Alaskan Stream and Kamchatka Current) are clearly evident. Eddy kinetic-mean kinetic energy ratios are low in the stream and along the western Bering Sea basin. An eastward flowing current occurred along the north flank of the Aleutian Islands; this flow was modified by inflow at the passes. Westward flow occurred north of 56 degree N; its source was the Bering Slope Current. The Kamchatka Current originated near 175 degree E along the Russian coast. Numerous eddies and meanders were observed in the Kamchatka Current; eddies were also present on the eastern side of the basin.

In 1992, reports from Looe Key (lower Florida Keys) indicated substantial activity by two of the four species seen spawning at the Flower Gardens. Observers reported no activity on Carysfort Reef (upper Keys). During each year, colonies in the FGBNMS released enormous amounts of eggs, sperm, or egg/sperm bundles after dark, eight evenings after the August full moon. Mass spawning of four species (Diploria strigosa, Montastrea annularis, M. cavernosa, and Stephanocoenia michelini) has been documented. Peak activity occurred after 2100 hours, but gamete release was seen between 1830 and 0030 hours. Minor spawning activity has occurred on the evening prior to the major event, prior to sunset on the most active dates, and on the evening following mass spawning, as well as seven days following the July full moon in 1991. Future research in the FGBNMS, as well as the Florida Keys and other western Atlantic reefs should include evaluations of the extent to which various coral species spawn, the timing of gamete release by various corals, the reproductive behaviors of different species, the dispersal patterns and fate of output, and fertilization success. It is important that researchers and resource managers evaluate and consider the implications of coral reproductive viability on reef ecosystem condition and health.

The institutional mechanisms for negotiating and carrying out the terms of CERCLA natural resource settlements are still in their infancy, and each case has a unique set of injuries, assigned damages, payout schedules, trustee council membership and operating procedures, and environmental conditions and constraints. One of the settlements that has made significant progress toward large-scale habitat enhancement has occurred in Elliott Bay, a busy, seriously impacted urban harbor in Washington State. The Elliott Bay case is unique among natural resource injury settlements because of the active involvement of two local governments, the City of Seattle, and Metro, who were named as defendants in a lawsuit brought by the National Oceanic and Atmospheric Administration (NOAA) on behalf of the natural resource trustees of Elliott Bay. Both local governments have maintained, and continue to operate, outfalls that discharge into Elliott Bay, and both entities were subject to attempts to recover damages under CERCLA. Following the filing of the lawsuit over injuries to the natural resources of the estuary, alleged to have resulted from the operation of these outfalls, the parties involved negotiated a consent decree settlement. The Elliott Bay/Duwamish Restoration Program has established a process to redress some of the injuries that were attributed to the operation of these outfalls. JF - Coastal management.

The OA gives statistically improved averages and the objective assignment of confidence intervals to these averages. The ability to assign confidence intervals is the main advantage of this method. Confidence intervals reflect how densely and uniformly an area is sampled during the averaging season. For the global average, the early part of the record (1860-1890) and the times of the two world wars have largest uncertainties. Analysis of OA-based uncertainty estimates shows that before 1930 sampling in the Southern Hemisphere was as good as it was in the Northern Hemisphere. From about 1930 to 1950, uncertainties decreased in both hemispheres, but the magnitude of the Northern Hemisphere uncertainties reduced more and remained smaller. After the early 1950s uncertainties were relatively constant in both hemispheres, indicating that sampling was relatively consistent over the period. During the two world wars, increased uncertainties reflected the sampling decreases over all the oceans, with the biggest decreases south of 40 degree S. The OA global SST anomalies are virtually identical to estimates of global SST anomalies computed using simpler methods, when the same data corrections are applied. When data are plentiful over an area there is no clear advantage of the OA over simpler methods. The major advantage of the OA over the simpler methods is the accompanying error estimates. The OA analysis suggests that SST anomalies were not significantly different from 0 from 1860 to 1900. This result is heavily influenced by the choice of the data corrections applied before the 1950s. Global anomalies are also near zero from 1940 until the mid-1970s. The OA analysis suggests that negative anomalies dominated the period from the early 1900s through the 1930s although the uncertainties are quite large during and immediately following World War I. Finally, the OA analysis shows significant positive global SST anomalies beginning in the late 1970s. The SST anomalies in the Indian Ocean and Southern Ocean poleward of 20 degree S make the strongest contributions to the positive global anomalies observed since the late 1970s. In contrast to the more recent period, the SST anomalies in the period from the early 1900s through 1940 were dominated by the anomalies in the Northern Hemisphere poleward of 20 degree N.

From white sturgeon egg collections, we determined that successful spawning occurred in all four years and that the estimated spawning period each year ranged from 38 to 48 days. The spawning period extended from late April or early May through late June or early July of each year. Spawning occurred primarily in the fast-flowing section of the river downstream from Bonneville Dam, at water temperatures ranging from 10 to 19 degree C. Freshly fertilized white sturgeon eggs were collected at turbidities ranging from 2.2 to 11.5 nephelometric turbidity units (ntu), near-bottom velocities ranging from 0.6 to 2.4 m/s, mean water column velocities ranging from 1.0 to 2.8 m/s, and depths ranging from 3 to 23 m. Bottom substrate in the river section where freshly fertilized eggs were most abundant was primarily cobble and boulder. White sturgeon larvae were collected from river kilometer (rkm) 45 to rkm 232, suggesting wide dispersal after hatching. Larvae were collected as far downstream as the upper end of the Columbia River estuary, which is a freshwater environment. Young-of-the-year (YOY) white sturgeon were first captured in late June, less than two months after spawning was estimated to have begun. Growth was rapid during the first summer; YOY white sturgeon reached a minimum mean total length of 176 mm and a minimum mean weight of 30 g by the end of September. Young-of-the-year white sturgeon were more abundant in deeper water (mean minimum depth greater than or equal to 12.5 m) of the lower Columbia River. The results indicate that a large area of the lower Columbia River is used by white sturgeon at different life history stages. JF - Fishery Bulletin AU - McCabe, GT Jr AU - Tracy, CA AD - Coast.

The SMPAR model was a compromise between simple surplus production and complex age-structured models. It was designed to give more precise biomass estimates for management of northern anchovy for which there are no age-composition data and only noisy abundance index data. We evaluated consistent bias in biomass and recruitment estimates, bias in recruitment estimates due to log transformation, and retrospective bias. Simple corrections based on bootstrap procedures were used to remove consistent bias and log transformation bias. Retrospective bias was not a significant problem. Results indicate that the SMPAR model estimates stock biomass more reliably than recruitment because abundance indices for northern anchovy contain little information about interannual recruitment variability. Asymptotic variance estimates calculated by inverting the Hessian matrix averaged 20% smaller than variances calculated by bootstrapping. Outliers in abundance data were the biggest source of uncertainty in biomass estimates. Simulation results indicate that our approach could be useful in a variety of situations.

WSR-88D data have been available to forecasters at five additional offices: Melbourne, Florida, and Sterling, Virginia (since January 1992); St. Louis, Missouri, and Dodge City, Kansas (since March 1992); and Houston, Texas (since April 1992). The performance of the severe local storm and flash flood warning programs at the six offices before and after the availability of the WSR-88D was measured quantitatively. The verification procedures and statistical measures used in the quantitative evaluation were those used operationally by the NWS. The statistics show that the warnings improved dramatically when the WSR-88D was in operation. Specifically, the probability of detection of severe weather events increased and the number of false alarms decreased. There was also a marked improvement in the lead time for all severe local storm and flash flood events. These improvements were evident throughout the effective range of the radar. Stratification of severe local storm data by severe thunderstorms versus tornadoes revealed an improvement in the NWS's ability to differentiate between tornadic and nontornadic storms when the WSR-88D was in operation. Four individual cases are examined to illustrate how forecasters used the WSR-88D to achieve the improved results. These cases focus on the unique features of the WSR-88D that provide an advantage over conventional NWS radars.

OPA calls for Area Contingency Plans which include detailed information on sensitive areas so that risks can be evaluated, protection priorities established, and mitigation strategies planned. NOAA has been working on guidelines for working on digital sensitivity maps and databases for use in Great Lakes and inland area planning. Digitally prepared sensitivity maps have been completed for Lake Ontario, Lake Michigan, and Lake Superior. Lake Huron is scheduled for completion in 1994. The major elements of sensitivity mapping include: 1) Shoreline-habitat maps for estuarine, lacustrine, and large river settings. In this approach, the shoreline type is mapped and ranked according to a scale of 1 to 10, from least to most sensitive to oil-spill impacts. 2) Watershed maps to differentiate among small rivers and streams. Stream reaches are mapped using a system that relates oil behavior and effects to stream characteristics such as gradient, discharge, and water turbulence, among others. 3) Data on sensitive biological and human-use resources focus on water-associated species, including those found in waterbodies, riparian vegetation, floodplain habitats, and all wetland types. The data are not limited to threatened and endangered species. There are major categories and sub-category assemblages for marine, aquatic, and terrestrial species. 4) Standardized formats for presentation of the data in digital and hardcopy map form for use in both emergency and planning applications .

Four liter bottles were incubated for up to four days under "natural light" or in the dark. Experimental treatments contained zebra mussels, 3-4 mu M mixed amino acid enhancement, or both zebra mussels and 3-4 mu M amino acid enhancement. Untreated water samples were incubated simultaneously as controls. Amino acids and ammonium were measured from the experimental treatments every 8-16 hours with fluorometric HPLC. As expected, ammonium concentrations increased in the presence of zebra mussels. Potential amino acid uptake rates were high (up to 70 nM h super(-1)) in the presence of zebra mussels, especially during the summer. Without zebra mussels, virtually no measurable amino acid uptake occurred.

All the chemical analyses are performed by participants involved in the NOAA QA Program. The inorganic analysis part of the QA program, presently directed by National Research Council Canada, includes a workshop and a minimum of 2 intercomparison exercises per year using fully matrixed blind material as well as reference material. Between 1985 and 1990, up to 17 trace elements were analyzed in the course of four rounds of intercomparison, including a total of 26 exercises. Through these exercises, we have documented the quality of the results obtained by the six laboratories contributing data to the NS&T program during that period (in general <+/-10% in accuracy and precision), giving us confidence in the comparability of most of the results. Sb and Sn, which are two very difficult elements to analyze, are displaying a larger variability. Finally, the results suggest that regular participation in the QA exercises has helped the laboratories to improve their performances over the years . JF - IAGLR, BUFFALO, NY (USA). p. 147. 1994.

The introduction of the exotic zebra mussel (Dreissena polymorpha) into western Lake Erie has impacted both of these limiting factors. Since both organisms require similar substrate for colonization the interaction/competition between the species is potentially great. The introduction of the filter-feeding zebra mussel has resulted in improved water clarity thus increasing light penetration and potentially expanding the vertical distribution of benthic algae. Field surveys were conducted to determine the areal and vertical distribution of Cladophora during the peak biomass period using SCUBA in the early 1980s, prior to the zebra mussel invasion. The surveys sites were revisited in 1992 and 1993 to determine if changes had occurred in the distribution of Cladophora since the introduction of zebra mussels and to investigate the interaction of Cladophora and zebra mussels on bedrock habitat. The study's primary result was that an increase in water clarity had not resulted in extending the vertical distribution of Cladophora due to competition for substrate with zebra mussels. Cladophora dominated the shallow areas from the splash zone down to approximately 1.5 m where competition for substrate began with zebra mussels. The bedrock lake bottom was generally dominated by zebra mussels at depths greater than 2 m even though adequate light levels were available for Cladophora colonization .

The average trend for the Northern Hemisphere during 1983-1991 was (11.6 plus or minus 0.2) ppbv yr super(-1), but the increase in 1992 was only (1.8 plus or minus 1.6) ppbv. In the Southern Hemisphere, the average increase (1983-1991) was (11.1 plus or minus 0.2) ppbv yr super(-1), and the 1992 increase was (7.7 plus or minus 1.0) ppbv. Various possibilities for a change in methane sources or sinks are discussed, but the most likely explanation is a change in an anthropogenic source such as fossil fuel exploitation, which can be rapidly and easily affected by man's activities.

Light and hydrogen peroxide increased the rate of dissolution of synthetic manganese oxides. Catalase decreased the rate. Light increased the dissolution rate with time to a maximal value of 4.6 per cent per h. Sunlight increased the rate of dissolution of natural manganese oxides. The effect was about 3-4 times larger than observed with synthetic oxides. The specific dissolution rate remained constant with time and was unaffected by humic acid addition or by photolytic removal of natural organic matter. Rates were unaffected by catalase. Rates for reductive dissolution of natural oxides by hydrogen peroxide were only a sixth of those for synthetic oxides. Photoreductive dissolution of natural oxides in seawater was not related to the photoproduction of hydrogen peroxide. Possible mechanisms for the photochemical reaction are discussed.

Although benthic habitats showed reduced sediment total organic carbon and metal contamination, increased summer bottom water dissolved oxygen and changes in the abundance of some benthic infaunal species, only winter flounder had statistically significant diet changes. Less significant results were found for red hake and for lobster no detectable, significant change or improvement in feeding was found at any of the stations. Although these results failed to reject the null hypothesis, the low statistical power of the tests for significant changes in red hake and lobster diets suggested a greater than 80 per cent chance of incorrectly accepting the null hypothesis at a 95 per cent confidence limit. The effect on predator health of substantial changes in quantitatively minor components of the diet after abatement needs to be assessed. There are 53 references.

No significant differences in concentrations of chlorinated hydrocarbons in blubber or liver, or toxic elements in liver were seen between whales stranded at urbanized sites or more pristine ones. Some whales had elevated concentrations of aluminium, iron and chromium in their stomach contents, but these were not associated with the urbanization of the site but with the geology of the sediments. The concentrations of potentially toxic chemicals in the grey whales, which filtered sediments to feed on benthic invertebrates, were lower than those in other marine mammals which feed on species such as fish.

Bioaccumulation and contaminant clearance data suggested that indicator species, exposure media and the chemical and physical properties of individual contaminants determined accumulation among the media tested. The difference in bioavailability of some contaminants could be adjusted by normalizing bioaccumulation to the amount of organic carbon in a source compartment. Assays which exposed organisms to aqueous representations of whole sediment could not be used to accurately predict the bioavailability of tested contaminants. There are 50 references.

Physical (length) and biochemical measures of growth (DNA and protein content) were determined. The sediments were analysed for organic chemical contaminants (aromatic hydrocarbons, pesticides, PCB, polar compounds) and metals. Radiolabelled PAH and PCB added to sediment were accumulated by exposed larvae. Sediment mixtures with high concentrations of contaminants were often acutely toxic. Exposure to diluted sediments resulted in decreases in growth and DNA content. The total protein content of larvae did not always reflect the changes observed in the DNA content of larvae after exposure to contaminated sediments. DNA content and the proportion of normal larvae were inversely related to PAH and PCB concentrations of test sediments. There are 47 references.

The model had to be physically-based to allow use in conditions other than those for which it was derived, while also reflecting conditions for which data did exist. Current ice dynamics models failed to meet these criteria. The proposed model was based on a prismatic ice pack heat balance, ice growth and temperature constraints and thermodynamic flux terms from companion water heat balance and storage equations. The model was integrated into an existing lake thermodynamics and 1-dimensional heat storage model and calibrated for Laurentian Great Lakes applications.

The probabilistic approach, based on implementing a probabilistic method with a deterministic initial dilution model, is compared with the worst case approach, in which a particular combination of parameters affecting initial dilution was specified and an associated initial dilution was calculated using a deterministic dilution model. In the probabilistic approach a framework was provided for combining data for the parameters which were often available in the form of time series or described in statistics. The result was a description of initial dilution as a function of cumulative or exceedance probability from which the exposure risk level for the marine environment could be estimated. The 2 approaches are compared in a case study of the Miami-Central outfall, Fla., U.S.A..

These are the Mellor and Yamada (1982) model (MY21/2 model), the McCormick and Savia (1981) eddy diffusion model (K), the Garbed (1977) integral mixed layer model (RWG), and the Thompson (1976) model (RT). Three of the models (K, RT, and RWG) were used in Erie lake simulations and the MY21/2 and RWG models were used in simulations of North Pacific data. The RWG, RT and MY21/2 models were highly correlated to each other in their response to wind deepening in the mixed layer. The K model failed to trace storm-induced deepening of the surface mixed layer. A general water quality model was derived from mass conservation principles to demonstrate how mixed layer models can be used to address water quality issues.

Water discharge variability was dominated by annual and seasonal time scales and could be explained by snowmelt runoff and precipitation patterns, whereas interannual variability was relatively unimportant. Nitrate concentration variability was strongest at decadal time scales and interannual variability was not monotonic. Variation in the nitrate flux which had a relatively noisy' signal due to weak covariability between water discharge and nitrate concentration exhibited a low-amplitude long-term modulation of a dominant annual cycle. Riverine forcing functions for freshwater discharge, nitrate concentration and nitrate flux could be hindcast or forecast at significant skill levels on seasonal or annual timescales. Nitrate concentration forecast was successful due to persistence of the signal at interannual time scales, while the comparatively unsuccessful forecasting effort for water discharge was due to a phase shift in the annual cycle.

The Antecedent Precipitation Index (API) model was the soil moisture model used in most NWS River Forecast Centres. Runoff, the output from the soil moisture model, was the input for the flow mode, the unit hydrograph technique being used. Tatum coefficient routing was used at the North Central River Forecast Centre (NCRFC). The co-ordination and dissemination of NCRFC forecast and guidance products is described. The challenges faced by NCRFC hydrologists in providing accurate forecasts during the Great Flood of 1993 is discussed. The API model needed extra attention to appropriately adjust results to get reasonable sub-basin runoff volume. Routing procedures were also tested as volumes exceeded calibrated values from previous floods. Overtopping levees caused difficulties in providing accurate flood crest predictions for points below the levee break. Availability and quality of data became a problem as gauges became inoperative and automated systems failed. Forecast bias and errors were determined at several locations. The skill and knowledge of operational hydrologists was important in model interpretation and in the preparation of accurate crest forecasts. Following the flood, new hardware systems, model initiatives and forecast procedures were a high priority for the NWS. Efforts at NCRFC included replacement of the API model by the Sacramento Soil Moisture Accounting model, evaluation of dynamic wave routing, the Hydrometeorological Analysis and Support function using radar-produced precipitation estimates, and Quantitative Precipitation Forecasts.

Measurements of stratospheric ozone in the tropics using electrochemical concentration cell (ECC) sondes before and after the eruption and the airborne UV differential absorption lidar (DIAL) system after the eruption are compared with Stratospheric Aerosol and Gas Experiment II (SAGE II) measurements from several years before the eruption and ECC sonde measurements from the year prior to the eruption to determine the resulting changes. Ozone decreases of up to 33% compared with SAGE II climatological values were found to be directly correlated with altitude regions of enhanced aerosol loading in the 16- to 28-km range. A maximum partial-column decrease of 29+ or -9 Dobson units (DU) was found over the 16- to 28-km range in September 1991 along with small increases (to 5.9+ or -2 DU) from 28 to 31.5 km. A large decrease of ozone was also found at 4 degrees to 8 degrees S from May to August 1992, with a maximum decrease of 33+ or -7 DU found above Brazzaville in July. Aerosol data from the visible channel of the advanced very high resolution radiometer (AVHRR) and the visible wavelength of the UV DIAL system were used to examine the relationship between aerosol (surface area) densities and ozone changes. The tropical stratospheric ozone changes we observed in 1991 and 1992 are likely be explained by a combination of dynamical (vertical transport) perturbations, radiative perturbations on ozone photochemistry, and heterogeneous chemistry.

AN - 36410914; 4360 AB - PURPOSE: The designation of marine waters and intertidal coastal areas adjacent to the Olympic Peninsula in Washington, and the submerged land thereunder, as a National Marine Sanctuary is proposed. The proposed sanctuary boundary would encompass an area of approximately 2,500 square nautical miles (8,577 square kilometers) of ocean waters and associated submerged lands over the continental shelf between the U.S./Canada border and the southern boundary of the Copalis National Wildlife Refuge. It would extend from Koitlah Point near Neah Bay, due north to the Canadian border, then in a northwesterly direction to a point just north of Buoy Juliette, where it would intersect with the Exclusive Economic Zone (EEZ). It would then follow the EEZ in a westerly then southwesterly direction, where it would intersect with the 100 fathom isobath at 48 degrees, 15 minutes north (N) latitude by 125 degrees, 41 minutes west (W) longitude, to a point at 47 degrees, 57 minutes N latitude by 125 degrees, 29 minutes W longitude. There, it would cut across the head of Juan de Fuca Canyon by continuing southeasterly in a straight line to a point at 47 degrees, 50 minutes N latitude by 125 degrees, 06 minutes W longitude, at which point it would follow a straight line in a more southerly direction to a point west of the mouth of the Caplis River at 47 degrees, 8 minutes N latitude by 124 degrees, 58 minutes W longitude, at which point it would continue due east to the shoreline. The coastal boundary of the sanctuary would be coterminus with the mean high tide line, extending up rivers to the point of tidal influence, except when adjacent to Indian reservations or state-owned lands, where it would extend only to the mean lower low tide line, cutting across the mouths of any rivers. All oil and gas leasing and development would be prohibited within the boundaries of the sanctuary, and additional restrictions would be placed on discharges and deposits, overflights, alteration of or construction on the seabed, historical resources, Navy use of Sealion Rock for bombing practice, and the taking of marine mammals, reptiles, and seabirds. POSITIVE IMPACTS: Through the designation of the Olympic Coast National Marine Sanctuary, an integrated program of resource protection, research, and education would be provided to assist in the long-term management and protection of the resources within the sanctuary. The sanctuary area is a highly productive, nearly pristine coastal environment that is important to the continued survival of several ecologically and commercially important species, including invertebrates, fish, marine birds, and marine mammals. NEGATIVE IMPACTS: Curtailment of commercial and other exploitative uses of sanctuary waters and lands would result in economic losses to current users. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), Marine Protection, Research, and Sanctuaries Act of 1972, as amended (33 U.S.C. 1401 et seq.), and Public Law 102-587.

AN - 36398817; 4374 AB - PURPOSE: The amending of the fishery management plan for the pollock, red hake, white hake, ocean pout, and windowpane flounder fisheries is proposed for three distinct regions of the North Atlantic: the Gulf of Maine, Georges Bank, and the portions of the continental shelf south of New England. The two main objectives of Amendment No. 5 are (1) to eliminate the overfished conditions of the principal groundfish stocks (cod, haddock, and yellowtail flounder) by reducing the rate at which fish are caught by 50 percent over the next five to seven years; and (2) to reduce the bycatch of harbor porpoise in the sink gillnet fishery. This final supplement to the final EIS of June 1986 considers the revision of the definitions of overfishing for each of the designated species. The proposed action would also address the decline in haddock which has taken place over the last three decades. It would also address the issue of extreme, wasteful discarding of large incoming age classes of certain stocks which has taken place periodically and for which the regulatory mechanisms in place are inadequate. Under the preferred alternative, overfishing of pollock would be defined as occurring when the target of 20 percent maximum spawning potential is not achieved. Overfishing of the other four species would be defined as occurring when the three-year moving average of the species abundance index from the Northeast Fisheries Science Center's bottom trawl survey falls within the lowest quartile of the time series. Under the preferred alternative, a moratorium would be established on vessel permits that would be retroactive to the control date of February 21, 1991, established by the New England Fishery Management Council; the moratorium would not apply to permits renewed during 1991. Exception would also be made for vessels fishing exclusively with fewer than 4,500 hooks per day (such vessels would be issued a ""hook gear only'' permit) and vessels catching less than the possession limit (such vessels would be issued a ""maximum possession limit'' permit). During the first two years after implementation of the preferred alternative, all permitted vessels would be required to declare 80 days, in blocks no smaller than 20 days each, in which they would remain out of the groundfish fishery. Furthermore, under the proposed amendment, larger mesh sizes would be imposed, and certain areas would be closed to fishing, in order to reduce fishing mortality. POSITIVE IMPACTS: Under the proposed amendment, with the goal of reducing the overall groundfishing effort by 10 percent during the first two years of implementation, the rebuilding of fishery stocks would be promoted. NEGATIVE IMPACTS: Imposition of a moratorium and quotas would restrict the immediate commercial capacity of the fishery, causing economic hardship for some users. Under the proposed amendment, the way in which the fishery is managed would change substantially; benefits would be redistributed among vessels of different sizes, vessels from different ports, and vessels that catch a different mix of fish.

AN - 76117172; 7903331 AB - DNA base lesions in hepatic chromatin formed upon whole-body irradiation of mice were studied. After gamma-irradiating (20-470 Gy) and killing animals, chromatin was isolated from their livers and analysed by GC-MS. Five pyrimidine- and five purine-derived DNA lesions were identified and quantified. These were 5-hydroxy-5-methylhydantoin, 5-hydroxycytosine, 5-(hydroxymethyl)uracil, 4,6-diamino-5-formamidopyrimidine, 7,8-dihydro-8-oxoadenine, 2-hydroxyadenine, 2,6-diamino-4-hydroxy-5-formamidopyrimidine, 7,8-dihydro-8-oxoguanine, thymine glycol and 5,6-dihydroxyuracil. Except for the latter two, the amounts of these compounds were increased significantly over control levels in the dose range of 100-470 Gy. Above 200 Gy, a deviation from linearity was observed, although the yields were increased in most cases up to 470 Gy. The modified bases that were identified are typically produced by hydroxyl radical attack on the DNA bases. This may indicate a role for hydroxyl radicals in their formation in vivo. These lesions may play a role in the biological consequences of ionizing radiation such as mutagenesis and carcinogenesis.

The measurements made during leg 2 on surface waters have been used to examine the internal consistency of the carbon dioxide system in these waters. The internal consistency of the measurements was examined by using various inputs of the measured parameters (pH-TA, pH-TCO (sub 2) , pH-fCO (sub 2) , fO (sub 2) -TA, fCO (sub 2) -TCO (sub 2) and TA-TCO (sub 2) ) to calculate the components of the CO (sub 2) system. The results indicate that the measurements have an internal consistency of + or -0.003-0.006 in pH, + or -5-7 mu mol kg (super - 1) in TA, + or -5-7 mu mol kg (super - 1) in TCO (sub 2) and + or -6-9 mu Atm in fCO (sub 2) if reliable constants are used for the dissociation of carbonic acid in seawater. These results indicate that our present understanding of the thermodynamics of the carbonate system in seawater is close to the present accuracy in measuring the various parameters of the system (+ or -0.002 in pH, + or -4 mu mol kg (super - 1) in TA, + or -2 mu mol kg (super - 1) in TCO (sub 2) and + or -2 mu Atm in fCO (sub 2) ).

Our survey included measurements of temperature anomaly, light attenuation (suspended particles), methane, hydrogen, iron, manganese, helium, and aluminum. We detected strong light attenuation plumes in two main regions: south of the Clipperton Transform Fault (CTF) from 9 degrees 27'N to 9 degrees 57'N and north of the CTF from 11 degrees 05'N to 11 degrees 35'N. However, the plumes at these two regions had very different physical and chemical characteristics. South of the CTF, where the ridge is thought to be magmatically robust, the plumes had very high ratios of (super 3) He/heat, methane/Mn and S/Fe. Plumes north of the CTF had much lower ratios of (super 3) He/heat, methane/Mn, and S/Fe. These striking differences in volatile/heat and volatile/metal ratios suggest that the plumes in the vicinity of 9 degrees 50'N were derived from a young, evolving hydrothermal system, while the activity at approximately 11 degrees 10'N is from an older, stable system. This survey demonstrated that water-column plume measurements can be used not only to accurately locate regions of hydrothermal activity, but also to determine the first-order chemical and physical characteristics of the hydrothermal fluids exiting from the seafloor.

AN - 76221722; 8309210 AB - Methods for extraction of cocaine, some of its metabolites, morphine, and codeine from hair and methods for analyzing the extracts have been investigated. Results of these studies have shown that extractions with 0.1N HCl are efficient at removing the target compounds from hair and appear to be as effective as enzymatic digestions that dissolve the hair. GC/MS with either electron ionization or chemical ionization was found to provide accurate and unambiguous determinations of the target compounds. Tandem mass spectrometry (MS/MS) also provided accurate results when performed on extracts from hair, but results were ambiguous when MS/MS was performed on hair segments directly. Environmental issues, including the removal of powdered and vapor-deposited cocaine from the hair surface and the effect of various hair treatments on the levels of cocaine entrapped in hair, have also been investigated. Removal of cocaine deposited on hair was incomplete by all approaches tested, making differentiation of hair of cocaine users from hair with environmental exposure of cocaine difficult. Cocaethylene, a cocaine metabolite believed to be formed in the liver, was found in the hair of some cocaine users and may be a good marker for proving drug use. Common hair treatments, such as shampoos, conditioners, and peroxide bleaches, reduced cocaine levels in a fortified hair material by 60 to 80% after 30 treatments. Finally, to assist laboratories in evaluating the accuracy of their methods, two human hair reference materials with recommended concentrations of cocaine, benzoylecgonine, morphine, and codeine determined by GC/MS have been developed.

AN - 76139708; 8272858 AB - The cryogenic archival of biological specimens for retrospective analysis is of significant value for present and future research on population genetics, pathology, systematics, toxicology and environmental monitoring. This realization is emphasized by the increasing support of this activity by various government agencies, institutions and international groups. The international Arctic community is no exception. Canada has been conducting such activities in association with environmental monitoring programs for many years. Similar efforts appear to be underway in other polar nations. From the perspective of the United States Arctic, the Alaska Marine Mammal Tissue Archival Project (AMMTAP) was the earliest organized effort to develop an environmental specimen bank specifically designed for longterm archival of biological specimens under cryogenic conditions. The AMMTAP emphasizes use of standardized rigorous sampling and archival protocols, procedures that minimize contamination of samples during collection and maintaining a detailed record of sample history. The development of this specimen bank, recent activities of this project and other cryogenic specimen banks being developed in Alaska are described.

AN - 76099118; 8248472 AB - Calculations of mass energy-transfer and mass energy-absorption coefficients for photon energies from 1 keV to 100 MeV have been developed, based on a re-examination of the processes involved after the initial photon interaction. The probabilities for the initial interaction are from the current photon interaction cross-section database at the National Institute of Standards and Technology. The calculations then take into account (1) electron binding effects on the Compton-scattered photon distribution; (2) the complete cascade of fluorescence emission after ionization events in any atomic subshell, including those associated with incoherent scattering and triplet production; and (3) the radiative energy losses of the secondary electrons and positrons slowing down in the medium, including the emission of bremsstrahlung, characteristic X rays from impact ionization, and positron in-flight as well as at-rest annihilation quanta. Consideration of the processes in (3) goes beyond the continuous-slowing-down approximation and includes the effects of energy-loss straggling. Results for the mass energy-absorption coefficient are compared with those from recent tabulations.

Ancillary surface-based measurements are presented in support of the aircraft data that show large increases in stratospheric optical depth attributed to the presence of volcanic aerosols. Visible optical depths greater than 0.2 were observed during flight segments flown above the tropopause. An inversion algorithm and the optical depth data are used to infer effective aerosol size distributions. The distributions tend to be bimodal, having a large-particle mode radius of about 0.50 mu m and a small-particle mode of higher concentration with radii less than 0.18 mu m. Surface measurements made during spring 1992 and 1993 are also used to estimate a time constant (e-folding time) of about 13.5 months assuming that the Arctic stratosphere's opacity decays exponentially; this estimate is larger than decay times observed following other major volcanic eruptions. Our results suggest that any climate perturbations in the Arctic caused by the eruptions of Pinatubo may be significant and will very likely persist longer than any volcanically-induced changes observed there during the past century.

When the alternating supplies (precipitation) and demands (potential evaporation) are viewed as random variables, it follows that soil-water storage, evaporation, and runoff are also random variables. If the forcing (supply and demand) processes are stationary for a sufficiently long period of time, an asymptotic regime should eventually be reached where the probability distribution functions of storage, evaporation, and runoff are stationary and uniquely determined by the distribution functions of the forcing. Under the assumptions that the potential evaporation rate is constant, storm arrivals are Poisson-distributed, rainfall is instantaneous, and storm depth follows an exponential distribution, it is possible to derive the asymptotic distributions of storage, evaporation, and runoff analytically for a simple balance model. A particular result is that the fraction of rainfall converted to runoff is given by (1 - R (super -1) )/(e (super alpha (1-R-1)) - R (super -1) ), in which R is the ratio of mean potential evaporation to mean rainfall and a is the ratio of soil water-holding capacity to mean storm depth. The problem considered here is analogous to the well-known problem of storage in a reservoir behind a dam, for which the present work offers a new solution for reservoirs of finite capacity. A simple application of the results of this analysis suggests that random, intraseasonal fluctuations of precipitation cannot by themselves explain the observed dependence of the annual water balance on annual totals of precipitation and potential evaporation.

Pinatubo are compared for changes which may result from increased sulfate aerosol surface area. Using ozone as a vertical coordinate and examining data at similar latitudes and seasons, elevated abundances of ClO are found at low latitudes (20 to 30 degrees N), an effect which decreases with increasing latitude. For the flights compared, there appear to be no differences, within the uncertainty of the measurements, at latitudes poleward of 40 degrees N. These results are consistent with the idea that the hydrolysis of N (sub 2) O (sub 5) on sulfate aerosols becomes saturated at moderate aerosol loadings.

Pinatubo had affected ozone at about 18 km. N (sub 2) O was used as a tracer to help distinguish between chemical and dynamical aerosol effects. At 20-45 degrees N in February 1992, ozone was about 10-20% lower than February 1989 and 1991, with respect to N (sub 2) O. Data from Aug. 1991-Mar. 1992 showed changes in ozone with respect to N (sub 2) O, but the magnitude of those changes was not correlated with the magnitude of the changes in aerosol surface area density.

Developmental instability measurements give a fairly accurate picture of the amount of stress experienced by a given species or ecosystem. The accuracy of the methodolgy can, however, be skewed by the effects of natural stressors. The effectiveness of developmental instability-based measurement strategies is evaluated based on data reflecting the influence of El Nino conditions on populations of Pacific Hake. A number of different criteria were used to establish developmental instability, including asymmetry of otolith length, width, growth rate, and weight.

AN - 15223311; 4302 AB - PURPOSE: The implementation of Amendment 5 of the fishery management plan (FMP) for the reef fishery in the Gulf of Mexico off the coasts of Florida, Alabama, Mississippi, Louisiana, and Texas is proposed. The FMP, as presented in the final EIS of August 1981, established prohibitions on the use of fish traps, roller trawls, and powerhead-equipped spear guns within an inshore-stressed area; set a minimum size limit of 13 inches total length for red snapper, with the allowance that for-hire boats were exempted until 1987 and each angler could keep five undersize fish; and established various data reporting requirements. This final supplement to the final EIS assesses the following actions proposed in Amendment 5: (1) establishing a three-year moratorium on the issuance of additional fish trap permits, and revising current rules regulating the use of fish traps (i.e., requiring that traps be carried to sea, tended, returned to shore after each trip, and be marked with a floating buoy); (2) establishing three special management zones (SMZs) off Alabama that encompass areas where more than 5,000 artificial reefs have been built and where fishing would be limited to three hooks per line; (3) establishing procedures for designating SMZs in other areas; (4) requiring that all nonmigratory finfish be landed with heads and fins intact to facilitate identification and compliance; (5) increasing the minimum size limit for red snapper from 13 to 16 inches; and (6) prohibiting all fishing in an area off southwest Florida where mutton snapper aggregate to spawn in May and June. POSITIVE IMPACTS: The plan would promote the availability of quality seafood to the consumer, as well as the rational and optimal biological and socioeconomic use of the region's fishery resources. Specifically, it would prevent overfishing and be beneficial to stocks and long-term productivity. NEGATIVE IMPACTS: The proposed restrictions would create some short-term economic hardships for commercial fishermen, whose incomes have already been reduced by overcapitalization under open access and overfishing of red snapper. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801). PRIOR REFERENCES: For the abstract of the draft supplement, see 93-0219D, Volume 17, Number 3.

Fiji's elderly population is projected to more than double between 1992 & 2020, due in part to improvements in national life expectancy & an epidemiological transition from a predominance of infectious diseases to more chronic, noncommunicable diseases, eg, heart disease & cancer. It is also noted that Fiji's rural population is older than its urban population, & that nearly 33% of the elderly participate in the labor force. 3 Tables, 6 Figures, 6 References. W.

The absence of a Cretaceous-Tertiary volcanic arc on the overriding plate suggests that much of the subducted carbon remains at depth today. Averaged over the length of the Alpine chain and the estimated amount of subduction that occurred in the past 125 m.y., approximately 10 (super 16) kg of carbon was buried because of collision in the Alpine region. Additional consideration of the Himalayan chain suggests that more than 10 (super 17) kg of carbon has been buried since 125 Ma by continent- continent collision. Transfer of this amount of carbon from atmospheric and sedimentary reservoirs into a deep-seated metamorphic reservoir may help explain the significant decrease in global surface temperature that occurred from 125 Ma to the present.

AN - 36406729; 4301 AB - PURPOSE: The amending of the management plan for the Atlantic sea scallop fishery of the Atlantic Ocean is proposed. The management unit consists of sea scallop resources from the shoreline to the outer boundary of the Exclusive Economic Zone (EEZ). The principal resource areas are the Northeast Peak of Georges Bank, westward to the Great South Channel, and southward along the continental shelf of the Mid-Atlantic. The overall objectives of the original management plan, implemented in May 1982, were to restore adult stock abundance and age distribution, to increase yield per recruit for each stock; to evaluate plan research, development, and enforcement costs; and to minimize adverse environmental impacts on sea scallops. This final supplement to the final EIS of May 1982 proposes to change the way Atlantic sea scallops are managed. Four alternatives are under consideration. In place of the current meat count controls, the amendment would seek to control aggregate fishing effort through a schedule of aggregate schedule reductions. Provisions would include granting permits to qualifying vessels, dealers, and captains of sea scallop vessels, and establishing a moratorium on scallop permits in order to cap the number of vessels fishing for scallops while the effort control program is in place. The effort control program would place limits on the number of days that vessels can spend at sea fishing for scallops. Fishing effort would be reduced from current levels over seven years until overall mortality falls below specified levels. Permitted vessels would be placed in one of three groups based on annual days at sea during 1985-90; vessels in each group would be allocated the same number of days, based on the overall condition of the fishery. Additional restrictions would involve limits on crew size and vessel upgrades; gear restrictions; and the required use of a vessel tracking system. POSITIVE IMPACTS: The amendment would reduce the current rate of fishing mortality, which is unacceptably high, to avoid drastic declines in scallop recruitment; it would replace the fish count standard with a standard that is easier to monitor and enforce. NEGATIVE IMPACTS: Imposition of effort controls would restrict the immediate commercial capacity of the fishery, causing some short-term economic hardships for some users. Some jobs would be lost if vessels excluded from the scallop fishery do not switch to an unregulated species. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

AN - 62504784; ED414014 AB - This report, based on the 1980 and 1990 Census of Population and Housing, Public Use Microdata Samples, presents statistics on America's U.S. children. The report focuses on family living arrangements and economic circumstances. Special attention is devoted to similarities and differences between non-Hispanic white children and non-Hispanic black or Hispanic origin children. Written summaries along with charts and graphs detail the demographic data. Key findings include: (1) throughout the past 50 years, fewer than one-half of children have lived in "traditional" families where the father was a full-time worker and the mother a full-time homemaker; (2) a majority live with two parents, but an increasing proportion have only one parent in the home; (3) nearly all who live with a father have a father who is employed, but many have fathers who work part-time; (4) most children who live with a mother only have a mother who works for pay; (5) for every child that lives in a "traditional" two-parent family, four children live in "nontraditional" two-parent families; (6) the proportion of children living in families with high incomes increased during the 1980s, as did the proportion living in low-income or poverty level families; and (7) whether they live with two parents or only a mother, black and Hispanic children experience much higher poverty rates than white children.

The helium isotope ratios exhibit a clear geographic variation, with relatively constant values of 7.8 R (sub A) along the southern JdFR increasing to a maximum of 8.8 R (sub A) at 46.9 degrees N on the Cobb Segment, and then dropping to values of approximately 8.0 R (sub A) at the Cobb Offset. Ratios along the Endeavour Segment further north are somewhat higher, averaging approximately 8.2 R (sub A) . Basalts dredged from Axial Seamount have (super 3) He/ (super 4) He = 7.9-8.4 R (sub A) , indicating that the seamount does not have a geochemical or isotopic signature distinct from other portions of the JdFR. This confirms that while Axial Seamount is the locus of excess magma generation, it is devoid of any hotspot or ocean island basalt geochemical signature. For the whole sample set, (super 3) He/ (super 4) He ratios show a negative correlation with (super 87) Sr/ (super 86) Sr. We attribute the geographical variations in (super 3) He/ (super 4) He to broad-scale heterogeneity in the mantle source region beneath the JdFR. Beginning at Axial Seamount and further north, (super 3) He/ (super 4) He shows a positive correlation with Fe (sub 8.0) , suggesting that melting dynamics in the underlying mantle may exert some control on the helium isotope ratios along part of our survey area.

[1986] to multi-beam sonar backscatter data. The use of principal components analysis, following spectral estimation, derives a single mappable index from correlated spectral parameters. This index can be mapped as a continuous field corresponding to geological observations in the area. This method allows for quantitative delineation of the neovolcanic zone and other zones of volcanic and tectonic activity from hull-mounted sonar systems.

Results indicate five significant subsidence events during the observation period (3.7 years), or an average of 1.35 events per year. The displacements range from 3-10 cm with durations of 10-14 days. These results indicate an active volcanic system and can be viewed as positive evidence for future attempts at seafloor volcanic observatories and response to active events on oceanic ridge crests. Advanced instrumentation based on multiple sensors has been deployed at the site to reinforce the results of this pilot experiment. Copyright 1993 by the American Geophysical Union.

Neither case is well documented because measurements of vent-field scale heat flux are scarce. We report here a new approach to hydrothermal plume monitoring sensitive to both progressive changes and hydrothermal events. From June 1991 to May 1992 we moored 35 self-contained temperature sensors and six current meters on seven moorings located in and around the plume from a vent field on the Cleft segment, Juan de Fuca Ridge. The hydrothermal plume was identified by a local temperature anomaly of 0.01 degrees to 0.03 degrees C in the lowermost 200 m of the water column. Plume heat flux, defined as the net advection of this temperature anomaly, averaged about 250 MW during the deployment. This flux is less than previous estimates and thus supports speculation that the heat flux is declining after a sudden reinvigoration triggered by a seafloor rifting event in 1986.

AN - 50173657; 1995-048631 AB - The continuous series of sea level at Key West, Florida commenced in 1913, but we have discovered sporadic measurements that date back to 1846. From records at the U.S. Army Corps of Engineers and the U.S. Coast and Geodetic Survey, the sea level series has been connected to a Summary (common) Datum. Thus, a gappy record of monthly and annual mean heights (H[t]), perhaps the United States' longest series over San Francisco (ca. 1854) or New York ( ca. 1856), can be tested to ascertain if the rise in relative sea level at this site is stationary. Applying first and second order least squares and two-phase regression analyses, we find that dH/dt is 0.19+ or -0.01 cm/yr, and that d (super 2) H/dt (super 2) = [9.6+ or -8.6].10 (super -3) cm/yr (super 2) ; the two-phase regression shows H[t] rising 0.15+ or -0.03 cm/yr before ca. 1925 and 0.23+ or -0.01 cm/yr afterwards. Neither the second-order regression coefficient nor d (super 2) H/dt (super 2) nor the two-phase calculation are significant above the 75% confidence level, but all three are weakly consistent with accelerated rise. For the epoch 1951-1987, Key West sea level, corrected for post-glacial rebound, is best explained by concurrent measurements of 0-1,000 db dynamic height anomaly change.

AN - 36412305; 4187 AB - PURPOSE: The improvement of Forest Development Road Number 30, which closely parallels the Salmon River in the Salmon National Forest in east-central Idaho, is proposed. The affected road, also known as the Salmon River Road, extends for 46 miles from the town of North Fork west to the Corn Creek campground and boating site. In 1980 Congress designated the Salmon River as a wild and scenic river, and the 46-mile segment within the proposed project area was classified as a recreational river. The Salmon River Road provides launch access and removal points for float-boaters using the Salmon River, and the only feasible access to private lands and numerous side drainages where other resource activities occur. The road is paved with an asphalt surface for approximately 16.8 miles and has a gravel surface for the remainder. Five alternatives (a No Action Alternative designated Alternative A, action alternatives designated B through D, and the preferred alternative, which is not otherwise designated) are considered in this final EIS. All of the action alternatives would involve improving eight existing recreation sites and developing up to eight new sites. Alternative B would involve a high level of roadway improvements, including paving approximately 29 miles of roadway, widening the roadway through the construction of retaining walls and some minor realignment, and installing guardrails. Alternative C would involve a moderate level of roadway improvements, including paving 9.8 miles of existing gravel road and applying crushed gravel to 19.8 miles of existing gravel road and spot paving through approximately 2.7 miles of residential, commercial, and recreation areas. Alternative D would involve a low level of roadway improvements, including paving 3.1 miles of existing gravel road and applying additional crushed gravel to the remaining 26 miles of gravel roadway; no spot paving would take place under this alternative below Pine Creek. The preferred alternative is a variation of Alternative D under which approximately 11,600 feet of spot paving would occur in residential and commercial areas. The estimated construction costs range from $2.2 million for Alternative D to $6.8 million for Alternative B. Recreation site developments would cost $1.7 million. POSITIVE IMPACTS: The proposed improvements would facilitate safe travel along the Salmon River Road and enhance the quality of recreational experiences associated with the Salmon River. The improvements would be in compliance with the forest plan. NEGATIVE IMPACTS: The estimated loss of wildlife habitat from the improvements beyond the road prism would range from 0.3 to 9.8 acres. Recreation site improvement and development, as well as the development of borrow sites, could disturb an additional 28 acres and 13.5 acres, respectively. The proposed retaining wall associated with Alternative B would encroach upon 2,300 feet of the floodplain, in contrast to that of Alternative C, which would encroach upon 200 feet of the floodplain. Increased turbidity and sedimentation would adversely affect fisheries under all of the action alternatives; among the species adversely affected would be two protected species, the sockeye salmon and chinook salmon. Some ponderosa pine would be lost under all of the action alternatives; they would also adversely affect the unique visual quality of the road and river corridor. Numerous archaeological sites and cultural resources near the road would also be adversely affected by the proposed improvements.

Preparation date: August 27, 1993 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STELLWAGEN BANK NATIONAL MARINE SANCTUARY MANAGEMENT PLAN, MASSACHUSETTS. AN - 15223246; 4213 AB - PURPOSE: The designation of the Stellwagen Bank and surrounding waters offshore of Provincetown, Massachusetts, as a national marine sanctuary is proposed. The sanctuary would consist of federal waters within a 453-square-nautical-mile area, extending 19 miles with a breadth of six miles at its widest point and lying approximately 3.5 miles northwest of Provincetown. The Stellwagen Bank is located in the extreme southwestern Gulf of Maine, which is formed by the bight of the northwest Atlantic coastline between Cape Cod, Massachusetts, and Cape Sable, Nova Scotia. Between Cape Ann and Cape Cod, in the southwest corner of the gulf, is Massachusetts Bay, 75 percent enclosed by land. The bay's most prominent submarine feature is Stellwagen Bank, which lies at the bay's eastern edge and partially blocks its mouth. The bank is a shallow, glacially deposited, primarily sandy-submerged feature, measuring nearly 20 miles in length. Water depths around the bank range from 65 feet to more than 300 feet. The resource protection plan for the sanctuary would involve cooperation with other agencies and organizations in formulating policies and procedures, including those related to enforcement of regulations affecting uses of the bank's resources. Sanctuary regulations would prohibit the following within the sanctuary: (1) the discharge or disposal of materials or substances from within the sanctuary boundary; (2) the discharge or disposal of materials or substances from outside the sanctuary boundary that subsequently enter the sanctuary and injure a sanctuary resource or quality; (3) the exploration for, development of, or production of industrial materials (e.g., sand and gravel); (4) the construction, placement, or abandonment on a seabed of any structure or material (e.g. pipelines or cables), or any alteration of the seabed; (5) the removal or alteration of or damage to (as well as attempt to cause the removal or alteration of or damage to) any historical or cultural resource; (6) the taking of any marine reptile, marine mammal, or seabird, except as permitted by the Marine Mammal Protection Act; (7) the at-sea ship-to-ship transfer of petroleum products (lightering); (8) the possession within the sanctuary of any historical or wildlife resource taken in violation of the Endangered Species Act, Marine Mammal Protection Act, or Migratory Bird Treaty Act; and (9) the interference with any investigation pursuant to regulatory enforcement. Additionally, certain activities not currently proposed for regulation would be identified in the designation document as subject to sanctuary regulations if, following designation, the need to regulate was demonstrated as necessary for the protection of the sanctuary resources and qualities. Research associated with the designation would include baseline studies, monitoring, and analysis and prediction projects to provide information needed to resolve management issues. Interpretive/educational programs would be directed at improving public awareness of the sanctuary's resources and the need to manage them wisely to ensure their continued viability and abundance. POSITIVE IMPACTS: Preservation of Stellwagen Bank as a national marine sanctuary would provide for a long-term integrated program of resource protection, research, and interpretation/education to assure comprehensive management and protection of the Stellwagen Bank system. Socioeconomic benefits could result from increased awareness of the Stellwagen Bank's ecological value and visitation by the public. NEGATIVE IMPACTS: NONE.

As a first approximation, the climatic changes observed after those earlier eruptions can be used to predict the changes to be expected from the more recent eruption. Ideally this intercomparison should be done with a common measurement system. Data from the advanced very high resolution radiometer (AVHRR) onboard the NOAA polar orbiting environmental satellite can be used to compare the optical properties of the aerosol layer produced by the two most recent major volcanic eruptions, El Chichon, early-April 1982, and Mount Pinatubo, mid-June 1991. In this paper, we use the error introduced into the multi-channel sea surface temperature (MCSST) fields by the volcanically-produced stratospheric aerosol layer to make a relative comparison of the size of the two eruptions. We also use aerosol optical thickness (AOT) estimates from the visible reflectance channel of the AVHRR to verify that the MCSST errors are indeed related to aerosol particle concentration in the stratosphere. During the first three months following both eruptions, these comparisons reveal that Mount Pinatubo introduced slightly less than twice (1.6 to 1.9) the amount of aerosol into the stratosphere as El Chichon.

During this period, large aerosol amounts due to the volcanic material injected into the stratosphere by Mt. Pinatubo were observed over Colorado. The observed NO (sub 2) column displays a strong anti-correlation with increasing amounts of stratospheric aerosol near 25-30 km for relatively low aerosol loadings. At higher aerosol loadings, the NO (sub 2) response appears to saturate, displaying little further reduction. The reasons for the altitude dependence of this relationship are probed with a one-dimensional stratospheric model, and it is shown that such a saturation response is to be expected for conditions where the heterogeneous reaction between N (sub 2) O (sub 5) and H (sub 2) O dominates the NO (sub x) chemistry, as in Prather [1992]. The results therefore provide evidence that heterogeneous reactions influence the chemical composition of the mid-latitude stratosphere, and in the general manner predicted by theory.

Juvenile Dover soles begin life in relatively shallow water on the continental shelf but move gradually down the continental slope into deeper water as they grow and reach sexual maturity. Large and old individuals may eventually reach depths greater than 1,500 m. The ontogenetic migration of Dover soles into deeper water gives rise to a general pattern of increasing fish size with water depth, but there are differences between sexes and locations. To describe these patterns in greater detail, we computed probability distributions for depth, length, and sex using research trawl data for Dover sole taken off central California and Oregon. Our results indicate that females live at greater depths than do males and that abundance of large Dover soles may be lower at depths where lowest oxygen concentrations occur. In addition, major differences in bathymetric demography exist between study sites due, we suggest, to differences in bottom topography. We used one group of probability distributions and logbook data for Oregon and central California in a simple model to demonstrate how depth of fishing and bathymetric demography complicate interpretation of length composition and other data from a commercial fishery. Results from the model indicate that depth-stratified assessment models may be required to interpret fisheries data for Dover sole and other species, like shortspine thornyhead Sebastolobus alascanus and sablefish Anoplopoma fimbria that undergo ontogenetic migration from shallow into deep water.

AN - 36414979; 4218 AB - PURPOSE: The amending of the Fishery Management Plan for the Shallow-Water Reef Fish Fishery of Puerto Rico and the U.S. Virgin Islands is proposed. This final supplement to the final EIS of February 1985 analyzes the effects of expanding the scope of the original plan by incorporating important components of the deep-water reef fish fishery and the marine aquarium trade into the management unit. Approximately 120 species would be added to the management unit, which currently contains the 64 most commonly landed species, and the plan would be retitled to cover all reef fishes. Other proposed management measures would restrict the gear used in collecting marine aquarium fishes to hand-held dip nets and slurp guns; specify that fish traps be built with two escape openings, utilizing wire panels and degradable fasteners; require an annual permit for and the periodic reporting of the sale of reef fish, including marine aquarium fish; prohibit the harvest or possession of jewfish and certain heavily exploited aquarium fishes; close additional red hind aggregation areas during the December-through-February spawning season; prohibit the harvest of mutton snapper off St. Croix from March through June of each year; establish marine coral reef reserves at strategic locations to be specified in a future amendment; and prohibit the unauthorized introduction of exotic species into marine waters. POSITIVE IMPACTS: The restrictions would help prevent overfishing and would restore stability to fisheries in the area from the shoreline to the edge of the insular platform; catch rates have declined in that area in recent years. Restrictions imposed on marine aquarium species would protect those species as well as others; the most widely used collecting methods employ chemicals that could damage the reef habitat and kill associated fishes and invertebrates. NEGATIVE IMPACTS: Although the conservation measures would eventually benefit the commercial fishing and aquarium fish industries, both industries would experience short-term economic hardships from the restrictions.

AN - 36408204; 4182 AB - PURPOSE: The implementation of a management plan to protect the habitat of late-successional-forest- and old-growth-forest-related species within the range of the northern spotted owl is proposed for lands managed by the Forest Service (FS) and the Bureau of Land Management (BLM) in the Pacific Northwest and northern California. A No Action Alternative and ten action alternatives developed by the Forest Ecosystem Management Assessment Team are considered in this draft supplement to the final EIS of January 1992 supplementing a final EIS issued by the FS for the Pacific Northwest region, and six draft EISs issued by the BLM in August 1992 for individual districts in Oregon. The preferred alternative (Alternative 9) would establish a management direction that corresponds with the plan announced by President Clinton in July 1993. This alternative would retain approximately 7.0 million acres reserved by Congress as national parks, wildlife refuges, and other specially designated areas. Another 7.1 million acres would be managed as late-successional reserves; some level of silvicultural treatment would be permitted in stands less than 80 years old in order to accelerate the development of old-growth-habitat characteristics, but all actions would require review by an interagency oversight team. The salvage of dead trees would generally be limited to areas where catastrophic losses exceeded ten acres. Approximately 1.5 million acres would be managed as adaptive management areas; each of these areas would have a different emphasis in its prescription, such as maximizing the amount of late-successional forests or improving riparian conditions through silvicultural treatments. Ten areas of federal land ranging in size from 84,000 to 400,000 acres have been identified as adaptive management areas. Approximately 2.2 million acres would be managed as riparian reserves, providing a buffer along all streams, wet areas, ponds, lakes, and unstable and potentially unstable areas. Finally, roughly 4.9 million acres would be managed as matrix areas, in which some levels of timber harvesting and other silvicultural treatment would be permitted. POSITIVE IMPACTS: Protection of old-growth habitat under the preferred management scheme would ensure the continued existence of the endangered northern spotted owl, the marbled murrelet, and other species dependent on late-successional and old-growth forest. The proposed limitations on timber harvests would benefit the watershed, fisheries, and soils. Similarly derived benefits would redound to recreational resources, cultural resources, and Native American religious sites. NEGATIVE IMPACTS: Some old-growth forest stands would be harvested under the preferred alternative. A major reduction in harvest activity would occur, however, which would cause the loss of jobs and income and could threaten the economic vitality of timber-dependent communities.

AN - 756824796; 13545-080320_0002 AB - PURPOSE: Amendment of the fishery management plan (FMP) for the western Pacific pelagic fisheries is proposed to modify the existing regulatory regime for the Hawaii-based shallow-set longline fishery. The FMP applies to fisheries operating in the U.S. Exclusive Economic Zone (EEZ) around American Samoa, Guam, Hawaii, the Northern Mariana Islands, and other possessions in the Pacific. The shallow-set longline fishery primarily targets swordfish on the high seas of the North Pacific. All measures currently applicable to the Hawaii-based fishery, which began operations as a model FMP in t he fourth quarter of 2004, provided for a suite of regulations intended to reduce the potential number and severity of interactions (hooking and entanglement) between fishing gear and sea turtles listed as threatened or endangered. Inter alia, vessel operators in the fishery must use large (18/0) circle hooks with a 10-degree offset and mackerel-type bait, may not make for than a total of 3,120 shallow-sets per year, must comply with a set certificate program, and may not interact with more than 17 loggerhead sea turtles or 16 leatherback turtles in a single year. The required use of circle hooks and mackerel-type bait has reduced sea turtle interaction rates by 90 percent for loggerheads, 83 percent for leatherbacks, and 89 percent for both species combined. Since the gear restriction has proven so effective, the Council now wishes to consider a range of alternative shallow-set regimes that would allow increased fishing effort and changes to other aspects of the regulatory regime. The proposed regulatory changes also respond to a petition to the Council from the Hawaii Longline Association including suggested modifications of the FMP. Categories of alternatives include shallow-set effort, administration of fishery participation, and season and area closures. Each category of alternatives includes a number of action alternatives as well as a No Action Alternative that would perpetuate the existing regime for that category. Based on the alternatives considered, the Western Pacific Regional Fishery Management Council has recommended the implementation of the following actions: 1) removal of the effort set limit; 2) implementation of new loggerhead and leatherback sea turtle interaction hard caps at 46 and 19, respectively; and 3) elimination of the set certificate program. No seasonal or area closures would be established. POSITIVE IMPACTS: The amendment would provide for increased opportunities for sustainable harvest of swordfish and other fish species, while continuing to protect the existence of threatened and endangered sea turtles and their habitat. Fishery closures, which have occurred in the recent past, would no longer be likely to be necessary. Fishery-based employment rolls would jump from 362 jobs to 685 to 837 jobs and employment income would increase from $2.0 million annually to $3.9 million to $5.1 million. Annual personal and corporate income would increase from $11.4 million to $22.1 million to $27.0 million. NEGATIVE IMPACTS: Sea turtle interactions would increase somewhat as compared to the interactions under the existing regime, but the increase would not be significant at the level of the turtle populations.

AN - 36409934; 4139 AB - PURPOSE: The amending of the fishery management plan (FMP) for the western Pacific pelagic fisheries is proposed. The FMP applies to fisheries operating in the U.S. Exclusive Economic Zone (EEZ) around American Samoa, Guam, Hawaii, the Northern Mariana Islands, and other possessions in the Pacific. Amendment 4 of the FMP, implemented in 1991, imposed a three-year moratorium on new participants entering Hawaii's longline fishery. A longline vessel operating within Hawaii's EEZ was required to have a limited-entry permit. This moratorium is scheduled to end in April 1994, at which time Hawaii's longline fishery would once again become an open-access fishery. The proposed Amendment 7 would establish a new longline limited-entry program for the fishery. The program would limit the number of permits to be issued for the fishery; allow free transferability of permits and unlimited upgrades of longline vessels; establish framework procedures for the adjustment of catch or effort in the event that new information demonstrated the need for such action; and authorize an official of the National Marine Fisheries Service (the Southwest regional director) to require that accommodations be made for placing observers on board permitted longline vessels. Longliners without limited-entry permits would be allowed to transit the EEZ or enter Hawaiian ports to obtain provisions, but they would be prohibited from off-loading their catch. The purpose of the amendment is to allow some increase in longline fishery operations over current conditions but to limit the growth until additional information is available concerning the impacts of the longline fishery on the stocks and possibly on other fisheries in Hawaii, particularly swordfish. There is also concern that increased landings by the longline fishery could have adverse effects on catches by troll and handline fishermen as well as on the survival of sea turtles and marine birds. Among the elements that could be manipulated to carry out a limited-entry program are (1) the number of limited-entry permits, (2) permit transferability, (3) vessel upgrade rules, and (4) application of limited entry differentially to separate sectors of the fleet or in different areas. While there are 24 possible combinations of these elements plus a null case (No Action Alternative), four alternatives are considered in this draft EIS: the proposed limited-entry program (the preferred alternative); continuation of the moratorium; issuance of special permits that would require new entrants to fish outside the EEZ; and establishment of open access. POSITIVE IMPACTS: The proposed amendment would lift many of the more restrictive provisions of the moratorium. The ability to transfer a permit or upgrade a vessel was severely limited under moratorium rules. In addition, area closures that were implemented after the moratorium took effect required longline fishermen to operate farther from shore. Taken together, these regulations have resulted in an unstable business environment and have increased safety concerns. The limited-entry program would provide for the continued monitoring of the industry and would not allow uncontrolled growth in the longline fleet, as would occur if open access were established. NEGATIVE IMPACTS: The limited-entry program would result in increased landings by the longline fishery, which in turn would cause troll handline prices to decrease somewhat. A greater risk of swordfish being overfished would occur under the limited-entry program than under a continued moratorium.

AN - 75997428; 8413035 AB - Shields and stents of metals with high atomic number, which are custom cast in molds from the melt, are the materials most widely used to protect surrounding tissues during treatment of skin or oral lesions with therapeutic electron beams. An improved fabrication method is to mix a polysiloxane-metal composite, which is readily cast at room temperature by combining a metal-powder/polysiloxane resin mixture with a hardening catalyst. The purpose of the present study is to compare the shielding effectiveness of two different metal-polysiloxane composites with that of conventional cast Lipowitz metal (50.1% Bi, 26.6% Pb, 13.3% Sn, 10% Cd). Also, a 2(3) factorial experiment was run to investigate the effects and interactions of metal particle size (20-microns vs 100-microns diameter), the atomic weight of the metal (304 stainless steel vs 70% Ag, 30% Cu alloy), and the presence or absence of a layer of unfilled polymer added to the forward-scatter side of the shield. The composites of different thicknesses were made by blending 90% (w/w) metal powder separately with 10% polysiloxane base and catalyst. A thin GafChromic dosimeter film was placed between the shielding material and a polystyrene base to measure the radiation shielding effect of composite disc samples irradiated with a 6-MeV electron beam normal to the flat surface of the disc. The results show that composite shields with the metal of higher atomic weight and density (Ag-Cu) combined with an additional unfilled layer are more effective than the stainless-steel composite with a similar additional unfilled layer, in terms of diminishing the dose at the surface of the polystyrene backing material.(ABSTRACT TRUNCATED AT 250 WORDS) JF - Medical physics AU - Farahani, M AU - Eichmiller, F C AU - McLaughlin, W L AD - ADAHF Paffenbarger Research Center, National Institute of Standards and Technology, Gaithersburg, Maryland 20899.

AN - 75847555; 8330324 AB - The formation and persistence of benzo[a]pyrene (BaP)- and 7H-dibenzo[c,g]-carbazole (DBC)-DNA adducts in liver of English sole (Pleuronectes vetulus) were investigated. BaP is a putative hepatocarcinogen in English sole based on its ability to induce formation of preneoplastic foci, while DBC is a hepatocarcinogen in mammals but whose carcinogenicity in fish is not known. English sole liver was sampled from 2 h through 84 days after a single intermuscular injection of a BaP and DBC mixture (100 mumol of each/kg body wt.), and DNA adduct levels were measured by the nuclease P1 version of the 32P-postlabeling assay. The major BaP adducts detected were from binding of BaP-7,8-diol-9,10-epoxide to DNA, whereas multiple uncharacterized DBC-DNA adducts were detected. Total adduct levels for both BaP and DBC reached a maximum at 2 days post exposure. The levels of DBC-DNA adducts were greater than the levels of BaP adducts at all time points and increased more rapidly than did the levels of BaP-DNA adducts. The DBC to BaP adduct ratio was 33 +/- 8.8 at 2 h and declined to 4.2 +/- 0.48 by 12 h post exposure. From 2 to 28 days, the levels of both BaP and DBC adducts declined with apparent half-lives of 11 and 13 days, respectively. There was no apparent decline from 28 to 84 days in the levels of the remaining BaP or DBC adducts; these persistent adducts represented 32 and 36% of maximum levels, respectively. These results provide the first data on the kinetics of adduct formation and removal of a carcinogenic nitrogen-containing polycyclic aromatic compound in fish. The results showing greater binding and similar persistence of DBC-DNA adducts compared to BaP-DNA adducts suggest that DBC may be hepatotoxic and potentially carcinogenic in English sole. In a separate experiment, the effect of multiple doses of BaP (30 mumol/kg body wt.) on the levels of hepatic BaP-DNA adducts showed that adduct levels increased linearly (r = 0.815, P = 0.0007) with 5 successive doses administered at 2 day-intervals and sampled 2 days after the last dose. The persistence of both BaP-DNA and DBC-DNA adducts in liver, together with the increase in BaP-DNA adducts in English sole exposed to successive doses of BaP, suggest that hepatic xenobiotic-DNA adducts in English sole are molecular dosimeters of relatively longterm environmental exposure to genotoxic polycyclic aromatic compounds.

These high CH (sub 4) and NH (super +) (sub 4) concentrations are attributed to the decomposition of sub sea- floor organic matter associated with sediments buried at an earlier stage of the ridge's evolution.

Estimates of the relative contribution of each discharge type, which are important for the accurate determination of local and global hydrothermal budgets, are difficult to obtain directly. In this paper we describe a new method of using measurements of hydrothermal tracers such as Fe/Mn, Fe/heat, and Mn/heat in high-temperature fluids, low-temperature fluids, and the neutrally buoyant plume to deduce the relative contribution of each discharge type. We sampled vent fluids from the north Cleft vent field on the Juan de Fuca Ridge in 1988, 1989 and 1991, and plume samples every year from 1986 to 1991. The tracers were, on average, 3 to 90 times greater in high-temperature than in low-temperature fluids, with plume values intermediate. A mixing model calculates that high-temperature fluids contribute only approximately 3% of the fluid mass flux but >90% of the hydrothermal Fe and >60% of the hydrothermal Mn to the overlying plume. Three years of extensive camera-CTD sled tows through the vent field show that diffuse venting is restricted to a narrow fissure zone extending for 18 km along the axial strike. Linear plume theory applied to the temperature plumes detected when the sled crossed this zone yields a maximum likelihood estimate for the diffuse heat flux of 8.9X10 (super 4) W/m, for a total flux of 534 MW, considering that diffuse venting is active along only one-third of the fissure system. For mean low- and high-temperature discharge of 25 degrees C and 319 degrees C, respectively, the discrete heat flux must be 266 MW to satisfy the mass flux partitioning. If the north Cleft vent field is globally representative, the assumption that high-temperature discharge dominates the mass flux in axial vent fields leads to an overestimation of the flux of many non-conservative hydrothermal species by about an order of magnitude.

Tsunamigenic earthquakes have larger seismic moments and T-phase spectral strengths than nontsunamigenic earthquakes. Pacific-wide tsunamigenic earthquakes had well-recorded water waves on the deep-ocean pressure gauges, while water waves for the regional tsunamis could be found only on coastal tide gauges in close proximity to the earthquake epicenters. Thresholds of T-phase spectral strengths required for tsunamigenesis are estimated for each of the areas investigated. On comparing tsunami heights, seismic moments, and spectral strengths for two Pacific-wide tsunamis generated by earthquakes with similar source locations, we note that the earthquake with the larger tsunami has the larger T-phase spectral strength but smaller seismic moment. We conclude that T-phase spectral strengths may be useful in estimating tsunami energy. Copyright 1993 by the American Geophysical Union.

These flocs were produced in a Couette-type flocculator under a variety of combinations of fluid shear and solid concentrations. In the calculation of floc porosities, a floc settling model was employed that can consider the effects of creeping flow through a floc on its settling speed. Results show that floc structure can be well described as a fractal with a fractal dimension of 1.53-1.64 for the floc size range tested. The effects of flocculation conditions, such as fluid shear and solid concentration, on floc porosity and structure were examined. It was found that floc porosity and fractal dimension were not influenced by solid concentration, but they increased as fluid shear decreased. Empirical expressions for the porosity of drilling mud flocs are obtained from both the floc settling model and Stokes' law. For solid volume fraction in flocs, the relative difference between these two expressions could be as much as 38%. However, the fractal dimensions estimated based on the two settling models are nearly the same.

To complement these field observations, we carried out laboratory time series experiments to determine the stability of V, As, Cu, and Cd in precipitates from hydrothermal plumes on the MAR and Juan de Fuca Ridge. For V and As, the metal/Fe ratio in plume particles remained uniform after sampling. In contrast to V and As, particulate Cu and Cd values decreased relative to Fe over time in laboratory studies using both plume particles and mound-derived sulfides. The combined field and laboratory results show that scavenging is an important removal mechanism for seawater V and As, whereas oxidative dissolution of hydrothermal precipitates in seawater adds Cu and Cd to the ocean.

Named the North and MIR relict zones, they are located about 4 km and 2 km northeast, respectively, of the known active high-temperature sulfide mound between water depths of 3625 and 3670 m on the rift valley floor near the base of the east wall. The North zone extends about 2 km along the northern end of the lower east wall. The zone includes two moundlike features up to 30 m high by 200 m in diameter imaged by side scan sonar within a 2-km-long line of discontinuous hydrothermal deposits comprising inactive toppled and standing chimneys, layered material, and patchy dark stains on sediment photographed by the camera-temperature tow. Several other moundlike features were imaged with the side scan sonar outside of the photographic coverage. The MIR relict hydrothermal zone 2 km south of the North zone, named after the MIR submersible used to investigate it, consists of three subzones: (1) a 200-m-wide area of diverse types of hydrothermal materials exposed by normal faulting at its western margin; (2) a 400-m-wide by 700-m-long central area of discrete groups of toppled and standing inactive sulfide chimneys up to 25 m high on a substrate of red metalliferous sediment and carbonate lutite; spires sampled on the highest chimneys are composed of coarse-grained, recrystallized sulfides dominated by pyrite and chalcopyrite which contain the first primary, free gold grains (2-3 mu m diameter) found at a hydrothermal site on a mid-ocean ridge; and (3) a 150-m-wide hummocky area of layered hydrothermal material with the appearance of low temperature precipitates and carbonate lutite with patchy dark stains at its eastern margin. The active sulfide mound, the North zone, and the MIR zone are each located on the fractured western margins of gentle, dome-shaped areas of pillow flows typically 500 m in diameter interpreted as summits of volcanic centers that may have supplied heat to drive adjacent hydrothermal activity. The distribution and size of the active and inactive hydrothermal zones of the TAG field, the chronology, and the characteristics of relict samples recovered indicate a history of at least 100 X10 (super 3) years of high-temperature hydrothermal episodes with multiple overprinting stages of mineralization accompanied by alteration.

The bacterial mats on polymetal sulfide surfaces contained unicellular and filamentous bacteria which appeared to use as their chemolithotrophic electron or energy source either dissolved reduced minerals from vent emissions, mainly sulfur compounds, or solid metal sulfide deposits, mainly pyrite. Moderately thermophilic Chemosynthetic activity was observed in carbon dioxide fixation experiments and in enrichments, but no thermophilic aerobic sulfur oxidizers could be isolated. Both obligate and facultative chemoautotrophs growing at mesophilic temperatures were isolated from all chemosynthetically active surface scrapings. The obligate autotrophs could oxidize sterilized MAR natural sulfide deposits as well as technical pyrite at near neutral pH, in addition to dissolved reduced sulfur compounds. While the grazing by shrimp on the surface mats of MAR metal sulfide deposits was observed and deemed important, the animals" primary occurrence in dense swarms near vent emissions suggests that they were feeding at these sites, where conditions for Chemosynthetic growth of their filamentous microbial epiflora were optimal. The data show that the transformation of geothermal energy at the massive polymetal sulfide deposits of the MAR is based on the lithoautotrophic oxidation of soluble sulfides and pyrites into microbial biomass.

At the TAG field, a Mn-oxide record, indicative of low temperature events, began at least 125,000 years and possibly 140,000 years ago with maximum intensities at 15,000, 7000 and 4000 years before present. High temperature events, giving rise to sulfide deposits, began about 100,000 years ago and have been intermittent to the present day. A presently active site has experienced intermittent pulses of activity every 4000 to 6000 years over the past 20,000 years. Decrease in activity is often marked by low temperature aragonite precipitation in chimney conduits at 4000, 7000 and 9000 years ago. After a period of quiescence lasting about 4000 years this site was reactivated about 50 years ago. The Snakepit field is much younger and no sulfides older than 4000 years have been recovered. Relict sulfide deposits are dated between 2000 and 4000 years old indicating this site was active during a quiescent period at TAG. Reactivation of Snakepit. took place about 80 years ago, and is presently concurrent with that of TAG. Comparison with hydrothermal sites on the East Pacific Rise suggests that on slow spreading ridges the major fracture systems focussing the hydrothermal discharge can be reactivated at intervals and new deposits precipitated on top of older ones, while on faster spreading ridges each pulse of activity is separated in space and time resulting in discrete deposits.

Two types of deposition of hydrothermal material have been identified and characterized. The first is sulfide material which has been rapidly deposited and is sometimes clearly turbiditic. This material exhibits high U/Fe and Eu/Sm ratios and low (super 230) Th/Fe and REE/Fe ratios. It is proposed that U is incorporated into the sulfides by diffusion through the oxidized coating with reductive fixation near the sulfide/oxide boundary. The second hydrothermal component is particulate fallout from the neutrally buoyant plume which is diluted by the background pelagic sedimentation. This component exhibits U/Fe ratios around 2 X 10 (super -5) , an order of magnitude greater than reported plume particulate levels, but the (super 230) Th/Fe, REE/Fe and Eu/Sm ratios are similar to plume values. Nd and Pb isotopes have been used to differentiate the hydrothermal and pelagic end-members within this sediment core. Copyright 1993 by the American Geophysical Union.

It appears that hydrothermal circulation at all spreading centers is an important exchange process between the ocean and the newly formed oceanic crust. This hydrothermal circulation may vary according to morphology and crustal composition and may also affect ridge constructional processes. The TAG (26 degrees N) and Snake Pit (23 degrees N) hydrothermal sites on the Mid-Atlantic Ridge (MAR) display Mn/CH (sub 4) ratios in overlying seawater similar to those of nonsedimented East Pacific Rise sites, i.e., about 0.2 mol/L. In contrast, large methane anomalies with very low Mn/CH (sub 4) ratios of 0.005 mol/L are associated with ultramafic topographic highs near 15 degrees N, close to the axis and on ultramafic walls of the rift valley. The association of ultramafic bodies and CH (sub 4) anomalies in seawater indicates active serpentinization processes. CH (sub 4) is produced during serpentinization according to the Fisher Tropsch reaction (Charlou et al., 1991). Many ultramafic rock assemblages have been sampled on the MAR away from fracture zones, in particular by the Deep Sea Drilling Project. Changes of mechanical properties and of density of uplifted deep material in the accreting plate boundary zone caused by serpentinization may play an important role in the construction of slow spreading ridges.

High-temperature fluids from seven vents on the East Pacific Rise (EPR) at 21 degrees N and 11 degrees -13 degrees N have delta (super 6) Li values ranging between -6 and -11 per mil, i.e., 3-7 per mil heavier than fresh basalt values. The intervent variations in Li concentration and isotopic composition correlate well with water/rock ratios. No temporal change in the isotopic value was observed between 1981 and 1985. Metabasalts show both Li depletion and enrichment relative to fresh basalt. They display light Li isotopic values which reflect incorporation of Li mobilized from fresh basalt. From these observations we conclude that the Li isotopic composition of submarine hot springs is controlled by a path-dependent process involving dissolution of primary minerals and precipitation of Li with alteration phases. delta (super 6) Li values of fluids from the Mid-Atlantic Ridge (-6 to -8 per mil) fall in the range of the EPR, indicating similar reaction controls at the two ridge systems. The lack of (super 7) Li enrichment in the fluids from slower spreading ridges indicates that Li is not recycled from older weathered crust. Thus the difference between the (super 3) He and (super 87) Sr/ (super 86) Sr based hydrothermal flux and the crustal transfer rate of Li cannot be reconciled by the inclusion of secondary Li from older crust.

Trace element geochemistry indicates the highly fractionated dike (feature 6) is genetically related to the other dikes and thus was intruded at or near the paleospreading axis. Hence, all previous events (features 1-5) can be constrained to have occurred at the rift axis, including large-scale tilting ( approximately 50 degrees ) of the sheeted dikes and extensional faulting. The [ (super 87) Sr/ (super 86) Sr] (sub initial) ratios from recrystallized whole rocks and from hornblende, epidote, and prehnite separates from veins display a systematic increase with relative age, from 0.7033 for altered gabbro screens and mafic dikes to 0.7049 for prehnite in the youngest oceanic fault rock. Calculated oxygen isotope fluid compositions for the same suite of samples range from delta (super 18) O (sub fluid) = +5 to -1 with time, indicating a change to a seawater-dominated hydrothermal system with time, consistent with observed increased permeability due to seafloor extensional faulting. The crosscutting relationships, alteration mineral assemblages, and isotopic data suggest (1) an early stage of high-temperature (> or =450 degrees C) hydrothermal alteration with low permeability (i.e., grain-scale flow), followed by (2) a decrease in temperature ( approximately 350to < or =200 degrees C), and an increase in permeability due to faulting and accompanied by tectonic tilting at the rift axis. The consistency of these crosscutting relationships at similar pseudo-stratigraphic levels at different localities in the Josephine ophiolite suggests that alternating magmatic and structural extension with synchronous retrograde alteration is common in crust formed at similar rates of spreading (slow- to intermediate-spreading centers), such as the modern Mid-Atlantic Ridge.

The vertical distribution of CH4 at stations located every 20-40 km is presented along this 1200-km-long section of the MAR. CH4 venting is clearly demonstrated. CH4-enriched fluids rise from vents as plumes; spreading is confined to the axial valley due to the topography of the MAR. CH4 contents from 45 nmol to 675 nmol/kg are measured in the buoyant plumes above the two active hydrothermal sites (MARK 23 degrees N; TAG 26 degrees N) known at present, whereas CH4 anomalies up to 3.6 nmol/kg are typically observed in plumes emitted either on the inner floor, on the walls, and/or at the top of the rift mountains along the studied ridge section. CH4 concentrations (45 mu mol to 144 mu mol/kg) in MARK and TAG vent fluids are of the same order of magnitude as those found in the East Pacific Rise fluids. Even though CH4 is known to be unstable with respect to oxidation by dissolved oxygen, and in spite of its microbial oxidation in plumes, these results confirm CH4 to be a good indicator to track hydrothermal plumes and to map the variation of hydrothermal activity along mid oceanic ridges. Moreover, between 12 degrees and 26 degrees N along the MAR, CH4 results show that while hydrothermal activity is present everywhere along the ridge, it is predominant near fracture zones (FZ) (Kane FZ, 15 degrees 20'N FZ). Comparison of CH4 tracer with total dissolvable manganese (TDM) tracer in plumes allows us to differentiate subseafloor hydrothermal processes. The high TDM/CH4 found above TAG and MARK areas is indicative of basalt-seawater interaction, while at 15 degrees N the low TDM/CH4 provides evidence of fluid circulation in ultrabasic rocks. CH4 data confirm the association between mantle degassing, hydrothermal activity, and serpentinization along this 12 degrees -26 degrees N section of the Mid-Atlantic Ridge.

On the basis of chemical compositions, two separate layers can be identified within the red-brown mud. The core position, X ray diffractometry, Pb isotope analyses, and elemental abundances all indicate that these two layers were derived from mass wasting of oxidized, originally sulphidic material from the slopes of the TAG hydrothermal mound. High concentrations (11-19 ppm) of seawater-derived U occur in both Fe-rich layers. These enrichments may derive from uptake of U linked to the oxidation of sulphide phases. Metal concentrations in the rich layer are lower than in the upper part of the core but higher than in open ocean pelagic sediments. The (super 230) Th (sub xs) /Fe, (super 231) Pa (sub xs) /Fe, and rare earth element/Fe distributions indicate that the hydrothermal input to the carbonate-rich layer is dominated by settling of suspended particulate material from the overlying hydrothermal plume. Such CaCO (sub 3) -rich sediments may record an important component of the flux of hydrothermal material to sediments of the Mid-Atlantic Ridge rift valley.

Al is removed from the hydrothermal end-members and is also stripped from the entrained seawater to produce levels of Al in the plume solutions about one fifth of normal seawater concentrations. The behavior of Al appears to be similar to that inferred for other anionic species (V, As, Cr, P) which exhibit constant element-iron ratios in hydrothermal plume particles and suggests that such elements are removed from seawater during the early stage of formation of hydrothermal plumes.

The combination of fine-scale sampling and rapid sedimentation produces radionuclide distributions that can be used to estimate the detailed chronology of particle transport processes in the Oahe reservoir system. A self-consistent and quantitative treatment of the (super 137) Cs data suggests processes to which characteristic times may be associated. Times that characterize system-wide processes include (1) an integration time of several years reflecting retention of the sediment-bound tracer in regions within or external to the reservoir, (2) a relaxation time of approximately 15 years reflecting a decreasing rate of sediment accumulation ascribed to shoreline stabilization, (3) a time of a few months characterizing the breadth of riverine signatures in cores due to integration effects in the Cheyenne River system and deltaic deposits, and (4) times of a few years associated with propagation of riverine load signatures along the embayment. The distribution of total sedimentary arsenic confirms the validity of the variable sedimentation model. In 1977, a tailings retention facility was built at the Homestake Mine site, and the unrestricted input of As ceased. As a result of this remedial action, the concentration of sedimentary As decreased dramatically. In the upper section of the core, above the depth represented by the year 1976, the concentration of As decreases tenfold. In this same core the distribution of lithologically discriminating chemical elements, calcium and vanadium, relate to major flow events in the Cheyenne River basin. Because there is minimal diagenesis of chemical constituents in these rapidly accumulating sediments, stable element signatures, in addition to radiotracers, may be used to reconstruct hydrologic events in drainage basins that contribute sediment to lakes and reservoirs.

The equations enable one to perform calculations directly with delta and epsilon quantities commonly reported in the literature. The main cause of the change occurring today is the combustion of fossil fuel carbon with lower delta (super 13) C values. The course of this isotopic anomaly in atmosphere and oceans can provide new constraints on the carbon budgets of these reservoirs. Recently published delta (super 13) C isotopic data of total inorganic carbon in the oceans [Quay et al., 1992] appear to lead to incompatible results with respect to the uptake of fossil fuel CO (sub 2) by the oceans if two different approaches to the data are taken. Consideration of the air-sea isotopic disequilibrium leads to an uptake estimate of only a few tenths of a gigaton C (Gt, for 10 (super 15) g) per year, whereas the apparent change in the ocean delta (super 13) C inventory leads to an estimate of more than 2 Gt C yr (super -1) . Both results are very uncertain with presently available data. The isotopic ratio has the advantage that the signal-to-noise ratio for the measurement of the uptake of the isotopic signal by the oceans is better than for the uptake of total carbon, The drawback is that isotopic exchange with carbon reservoirs that are difficult to characterize introduces uncertainty into the isotopic budget. The accuracy requirements for the measurements are high, demanding careful standardization at all stages. Copyright 1993 by the American Geophysical Union.

In May and August, at stations Papa (50 degrees N, 145 degrees W) and R (53 degrees N, 145 degrees W), the mean delta (super 18) O in the mixed layer was 23.84+ or -0.20 and 24.00+ or -0.24 per mil (versus standard mean ocean water) consistently more depleted than atmospheric saturation levels by about 0.4 per mil. This relative depletion is caused by input of photosynthetically produced O (sub 2) . A value for the isotopic fractionation effect during respiration (alpha (sub T) ) of 0.978+ or -0.006 was determined from the time rate of change of the concentration and delta (super 18) O of O (sub 2) in the mixed layer measured during August 1988. Below the mixed layer (100-280 m) the O (sub 2) concentration decreased with a corresponding increase in delta (super 18) O. Model derived values for alpha (sub T) over this depth region ranged from 0.980 to 0.988 and depended on the mixing model. The difference between alpha (sub T) determinations for the surface layer versus upper thermocline likely results from mixing model inaccuracies or different isotope fractionation effects during plankton and bacterial respiration. If the calculated mixed layer alpha (sub T) values apply oceanwide, then photosynthesis and respiration by the marine biota have a similar effect to land plants in maintaining the delta (super 18) O of atmospheric O (sub 2) at 23.5 per mil.

AN - 36410007; 4135 AB - PURPOSE: The implementation of Amendment 5 to the fishery management plan (FMP) for the reef fish fishery in the Gulf of Mexico off the coasts of Florida, Alabama, Mississippi, Louisiana, and Texas is proposed. The FMP, as presented in the final EIS of August 1981, established prohibitions on the use of fish traps, roller trawls, and powerhead-equipped spear guns within an inshore-stressed area; set a minimum size limit of 13 inches total length for red snapper, with the allowance that for-hire boats were exempted until 1987 and each angler could keep five undersize fish; and established various data reporting requirements. This draft supplement to the final EIS assesses the following actions proposed in Amendment 5: (1) establishing a moratorium on the issuance of additional fish trap permits, and revising current rules regulating the use of fish traps (i.e., requiring that traps be carried to sea, individually buoyed, tended, and returned to shore after each trip); (2) establishing special management zones (SMZs) off Alabama that encompass areas where more than 5,000 artificial reefs have been constructed and where fishing would be limited to three hooks per line; (3) establishing procedures for designating SMZs in other areas; (4) requiring that all nonmigratory finfish be landed with heads and fins intact to facilitate identification and compliance; (5) considering changes to vessel permitting requirements; (6) increasing the minimum size limit for red snapper from 13 to 16 inches; and (7) prohibiting all fishing in an area off southwest Florida where mutton snapper gather to spawn in May and June. POSITIVE IMPACTS: The plan would promote the availability of quality seafood to the consumer, as well as the rational and optimal biological and socioeconomic use of the region's fishery resources. Specifically, it would prevent overfishing and be beneficial to stocks and long-term productivity. NEGATIVE IMPACTS: Traps are used primarily by marine fishermen who harvest ornamental tropical fish for the aquarium trade. Few such fisheries operate in the Gulf, however, and those that do generally follow the proposed practices. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

From June 22 to July 16, 1992, a team of Canadian and U.S. scientists and engineers joined in an expedition to develop sampling capabilities for a HYSUB 5000 ROV in a mid-ocean ridge hydrothermal vent environment. Our experience on the Juan de Fuca Ridge is another starting point for pursuing the science capabilities of deep-water ROVs. The Remotely Operated Platform for Ocean Science (ROPOS) was built by International Submarine Engineering and is operated by the Institute of Ocean Sciences in Sidney, British Columbia. The cruise was staged off the National Oceanic and Atmospheric Administration's ship Discoverer, based at NOAA's Pacific Marine Center in Seattle, Wash. Support for the expedition came from the Department of Fisheries and Oceans Canada, the Department of Energy Mines and Resources Canada, the NOAA Vents Program, and the Natural Sciences and Engineering Research Council Canada.

The warming was not symmetric with respect to the equator, however, with greater warming south than north of the equator. The warming following El Chichon was slightly greater than following Agung in all climatic zones except the south polar zone. Results for Pinatubo are preliminary because of the recency of the eruption, but in north extratropics and tropics the warming following this eruption is indicated to be comparable to the warming following Agung and El Chichon. However, in south temperate and polar zones the warming is considerably greater following Pinatubo, perhaps reflecting a contribution from the eruption of Cerro Hudson in Chile. Globally, therefore, the low-stratospheric warming following Pinatubo is greater than following Agung or El Chichon. Based on a 10-station tropical radiosonde network with data to greater heights, the warming following El Chichon exceeded the warming following Agung to a height of at least 31 km, the difference in warming increasing with height. The warming following Pinatubo is similar to that following Agung to a height of 24 km, but thereafter is indicated to become less, an unexpected result to be reexamined as more data become available.

Upwelling results in high biological productivity and a distinctive assemblage of plankton species in the surface waters off Oman that are preserved in the sediments along the Oman continental margin, creating a geologic record of monsoon-driven upwelling. Sediments recovered from the Oman continental margin during Ocean Drilling Program leg 117 provide an opportunity to examine how upwelling has varied during the late Quaternary, spanning a longer interval than piston cores recovered prior to the ODP cruise. Variations in foraminifer shell accumulation and in the relative abundance of Globigerina bulloides indicate dominant cycles of variation at 1/100 kyr, the dominant frequency of glacial-interglacial variations, and at 1/23 kyr, the frequency of precessionally driven cycles in seasonal insolation. The strongest monsoon winds (indicated by increased upwelling) occurred during interglacial times when perihelion was aligned with the summer solstice, an orbital change that increased the insolation received during summer in the northern hemisphere. During glacial times upwelling was reduced, and although the precessional cycles were still present their amplitude was smaller. At both frequencies the upwelling cycles are in phase with minimum ice volume, evidence that glacial-interglacial climate changes also include changes to the climate system that influence the low-latitude monsoon. We attribute the decrease in the monsoon winds observed during glacial times to changes in bare land albedo over Asia and/or to changes in the areal extent and seasonal cycle in Asian snow cover that decrease the summer land-sea temperature contrast. Other mechanisms may also be involved. These new upwelling time series differ substantially from previous results, however the previous work relied on cores located farther offshore where upwelling is less intense and other physical mechanisms become important. Our results support the observations derived from atmospheric general circulation models of the atmosphere that indicate that both glacial boundary conditions, and the strength of summer insolation are important variables contributing to cycles in the monsoon winds during the late Quaternary.

We used the model to detect possible influences of gross climatic conditions and contaminant loadings (particularly of metals and organochlorines) on reproduction in these three stocks. Data included several decades of annual estimates of recruitment and stock size, monthly measures of climate, and annual estimates of contaminant loadings; the model included a compensatory stock-size component before adding environmental effects. The study was meant to generate, rather than test, hypotheses. For the chub mackerel stock, we detected climate influences, but no contaminant influences, on reproductive success, which was usually high during conditions typical of El Nino-Southern Oscillation events. For the northern anchovy stock, we detected no climate or contaminant influences on spawning success; however, the negative results may reflect low statistical power, rather than absence of contaminant influences. For spawning success in the Pacific sardine stock, we detected no consistent climate influences, but we found a strong negative correlation with contaminant loadings. This result is consistent with the hypothesis that contaminant loadings accelerated the collapse of the Pacific sardine stock while it was under stress from severe overfishing. Although many scientific questions about validation of models, mechanisms of action, and identity of specific deleterious contaminants remain to be answered, the observed data are well described by the hypothesis of contaminant-mediated decline.

AN - 36390289; 4060 AB - PURPOSE: The implementation of a fishery management plan for the white shrimp population along the Atlantic coast from Florida to the North Carolina/Virginia border is proposed. The shrimp industry that operates in these waters is based almost entirely on three shallow-water species: the white shrimp, brown shrimp, and pink shrimp. The white shrimp population is occasionally decimated by severe winter weather; continued fishing for the few remaining adults is believed to reduce recruitment and the more valuable fall production. Under the proposed plan, overfishing would be indicated whenever the overwintering white shrimp population within a state's waters declines by 80 percent or more following severe winter weather. When such conditions occur, states could request closure of the economic zone adjacent to their closed state waters and establish a buffer zone extending seaward from shore for 25 nautical miles, inside of which no trawling would be allowed with a net less than four-inch stretch mesh. Vessels trawling inside the buffer zone would not be permitted to have a shrimp net on board. The proposed plan includes various research recommendations for studying the white shrimp population, and the effects of changes in habitat conditions and the inadvertent introduction of exotic shrimp species and diseases. The plan would also address the bycatch of nontarget finfish, invertebrates, and threatened, protected, and endangered species; the loss and/or alteration of shrimp habitat and the degradation of water quality through pollution; and the continuing threat to critical shrimp habitat from human activities, including beach renourishment, dredge, and fill projects. POSITIVE IMPACTS: Closure of the fishing zone in spring months following a severe winter would substantially increase the size of the subsequent white shrimp catch over the levels expected if closure had not occurred; the yield would increase by approximately 6.8 million pounds over the anticipated yield if no action were taken. NEGATIVE IMPACTS: Closure would force shrimpers to seek alternative sources of revenue in the spring months; revenue losses to shrimpers in a given economic zone during a given year's spring months would range from $577,911 to $759,973.

AN - 36410974; 4061 AB - PURPOSE: The amending of the fishery management plan for the pollock, red hake, white hake, ocean pout, and windowpane flounder fisheries is proposed for three distinct regions of the North Atlantic: the Gulf of Maine, Georges Bank, and the portions of the continental shelf south of New England. This draft supplement to the final EIS of June 1986 would revise definitions of overfishing for each of the designated species. Under the preferred alternative, overfishing of pollock would be defined as occurring when the target of 20 percent maximum spawning potential is not achieved. Overfishing of the other four species would be defined as occurring when the three-year moving average of the species abundance index from the Northeast Fisheries Science Center's bottom trawl survey falls within the lowest quartile of the time series. Under the preferred alternative, a moratorium would be established on vessel permits that would be retroactive to the control date of February 21, 1991, established by the New England Fishery Management Council; the moratorium would not apply to permits renewed during 1991. Exception would also be made for vessels fishing exclusively with fewer than 4,500 hooks per day (such vessels would be issued a ""hook gear only'' permit) and vessels catching less than the possession limit (such vessels would be issued a ""maximum possession limit'' permit). During the first two years after implementation of the preferred alternative, all permitted vessels would be required to declare 80 days, in blocks no smaller than 20 days each, in which they would remain out of the groundfish fishery. Furthermore, the proposed amendment would impose larger mesh sizes and close certain areas to fishing in order to reduce fishing mortality. POSITIVE IMPACTS: With the goal of reducing the overall groundfishing effort by 10 percent during the first two years of implementation, the proposed amendment would promote the rebuilding of fishery stocks. NEGATIVE IMPACTS: Imposition of a moratorium and quotas would restrict the immediate commercial capacity of the fishery, causing economic hardship for some users. The proposed amendment would substantially change the way in which the fishery is managed, and would redistribute benefits among vessels of different sizes, vessels from different ports, and vessels that catch a different mix of fish.

AN - 75600212; 8383005 AB - We investigated whether phorbol-12-acetate-13-myristate (PMA)-activated human polymorphonuclear leukocytes (PMNs) induce base modifications in target cell DNA in vivo. Human PMNs produced 9.4 +/- 0.8 (SD) nmol of H2O2/10(6) cells during 50 min of exposure to 2 micrograms/ml PMA and 13.7 +/- 2.8 nmol/10(6) cells during exposure to PMA plus 5 mM NaN3. Neither nonstimulated PMNs, nor PMA alone, nor NaN3 alone induced base modifications in chromatin-associated DNA of human Ad293 cells above control levels, when assayed by gas chromatography/mass spectrometry with selected-ion monitoring. However, a 60-min exposure to 1.7 +/- 0.4 x 10(6) PMNs/ml in the presence of 2 micrograms/ml PMA induced a 2-3-fold increase in the level of all modified bases detected by gas chromatography/mass spectrometry with selected-ion monitoring. The guanine-derived products 8-hydroxyguanine and 2,6-diamino-4-hydroxy-5-formamidopyrimidine, and the adenine-derived product 4,6-diamino-5-formamidopyrimidine were induced to the highest levels among those bases detected. These data demonstrate that exposure to activated PMNs causes DNA base modifications in target cells in vivo typical of those induced by hydroxyl radical attack. The induction of potentially promutagenic modified bases may contribute to the mutagenicity of activated PMNs.

AN - 36388681; 4041 AB - PURPOSE: The improvement of Forest Development Road Number 30, which closely parallels the Salmon River in the Salmon National Forest in east-central Idaho, is proposed. The affected road, also known as the Salmon River Road, extends for 46 miles from the town of North Fork west to the Corn Creek campground and boating site. In 1980 Congress designated the Salmon River as a wild and scenic river, and the 46-mile segment within the proposed project area was classified as a recreational river. The Salmon River Road provides launch access and removal points for float-boaters using the Salmon River, and the only feasible access to private lands and numerous side drainages where other resource activities occur. The road is currently paved with an asphalt surface for approximately 16.8 miles and has a gravel surface for the remainder of its length. Four alternatives, including a No Action Alternative (Alternative A), are considered in this draft EIS. After completion of the final EIS, an alternative would be selected for each of six road segments. Under all three of the action alternatives, eight existing recreation sites would be improved and eight new sites would be developed. Under Alternative B, actions would include a high level of roadway improvements, including paving approximately 29 miles of roadway, widening the roadway through the construction of retaining walls and some minor realignment, and installing guardrails. Under Alternative C, actions would include a moderate level of roadway improvements, including paving 9.8 miles of the existing gravel road, constructing shorter segments of retaining walls than under Alternative B, and applying additional crushed gravel and performing spot paving in some sections (approximately 2.7 miles). Under Alternative D, actions would include a low level of roadway improvements, including paving 3.1 miles of the existing gravel road and applying additional crushed gravel to the remaining 26 miles of gravel roadway; no spot paving would occur under this alternative. A different alternative could be selected for each road segment. The estimated construction costs range from $2.2 million for Alternative D to $3.7 million for Alternative C, and up to $6.8 million for Alternative B. Recreation site developments would cost $1.7 million. POSITIVE IMPACTS: The proposed improvements would facilitate safe travel along the Salmon River Road and enhance the quality of recreational experiences associated with the Salmon River. The improvements would be in compliance with the forest plan. NEGATIVE IMPACTS: The estimated loss of wildlife habitat from the improvements beyond the road prism would range from 0.3 to 9.9 acres. Recreation site improvement and development, as well as development of borrow sites, could disturb an additional 28 acres and 13.5 acres, respectively. The proposed retaining walls associated with Alternative B would encroach upon 2,300 feet of the floodplain, in contrast to those associated with Alternative C, which would only encroach upon 200 feet of the floodplain. Increased turbidity and sedimentation would affect fisheries under all the action alternatives; among the species affected would be two protected species, the sockeye and chinook salmon.

Ba concentrations generally increase with depth in all three basins and are not significantly affected by adsorption/uptake on Mn and Fe oxyhydroxides in redox interfaces. Uptake of Ba (probably as baryte in organic matter) and sinking and dissolution with water mixing account for the Ba profiles with depth. Comparisons with other anoxic sites are discussed.

Three-dimensional analysis of these data clearly shows a distinct zone of reduced magnetization directly beneath the active mound. This magnetization low is consistent with the highly altered upflow zone of a hydrothermal vent system that feeds the actively venting mound structure. In contrast, the sea surface magnetic anomaly is associated with a broad 2X8 km magnetization low elongated along the axis, that includes both the active and inactive mounds. The short-wavelength (250 m), near-bottom magnetic anomaly over the active mound is far too small to produce the long-wavelength (8 km) sea surface magnetic anomaly at TAG however, and even a collection of mounds with similar magnetic structure cannot produce the magnetic moment needed to generate the sea surface anomaly. Other hypotheses, including reversely magnetized crust and structurally thinned crust could account for the sea surface anomaly but are considered unlikely. The existence of vigorous hydrothermal activity at TAG and the lack of microseismic activity in the TAG area suggests that thermal demagnetization is the prime contributor to the sea surface anomaly. The thermal halo associated with a largely solid but still hot intrusion would provide sufficient demagnetization on a kilometer scale to produce the long-wavelength sea surface anomaly. Pervasive alteration at depth would also be an important factor in the destruction of crustal magnetization and is the only way that such a long-wavelength magnetic signal could be preserved in the crust. The overall model of crustal magnetization at a hydrothermal field with discrete zones of demagnetization in the upper crust and a broader zone of demagnetization at depth is consistent with studies of hydrothermal systems in ophiolite suites. These studies show narrow alteration pipes in the upper crust feeding the exhalative seafloor deposits and pervasive alteration at depth which commonly have associated late-stage intrusive bodies [1]. While detailed magnetic surveys may provide some clues to the location of oceanic hydrothermal upflow zones, only drilling will ultimately test these hypotheses.

It leads to a source model for an opening crack consisting of a center of dilatation and a double force without moment. The work on deformations around a tension crack in a homogeneous half-space is combined with the results for subsurface deformations in a layered half-space. Thus, a method is obtained to calculate the displacement and stress throughout a medium accounting for vertical changes in its elastic parameters. By superposition of the elastic fields of point sources, an extended crack or a system of cracks can be simulated. The results agree very well with those for inclined crack point sources in a homogeneous half-space. Surface displacements, subsurface displacement and tilt fields obtained for realistic situations are measurable by existing methods. The influence of layering is demonstrated in comparison with homogeneous models and the results of a model consisting of several point cracks are given. The method can be applied to the forward modeling of crustal deformation caused by dike injections in volcanic areas, by mid-ocean ridges, and by continental rifts. Thus, the so-alled magma chamber of a volcano can be modeled as a system of cracks instead of a cavity. Moreover, the deformational effects of dilatancy in rock and the opening of cracks during hydrofracturing can be simulated. Copyright 1993 by the American Geophysical Union.

While it is possible to specifically design mantle thermal profiles that produce relatively constant viscosity, temperatures deduced from parametric and/or full numerical simulation of convection predict steep increases of viscosity with depth. The most ubiquitous trend is an increase in viscosity from about 800 to 900 km depth to the top of the D" layer. Predicted increase of viscosity in this portion of the lower mantle ranges from a factor of 10 (super 2) to 10 (super 4) . Precise estimates are impossible due uncertainty in determining activation volume V (super *) and activation energy E (super *) . Zeroth-order extrapolation of a creep law to lower mantle conditions requires the assumption that diffusion of a single ionic species controls dislocation mobility. The extrapolation is useful in spite of its great uncertainty. Our rationale consists of two essential elements: (1) Creep laws with depth-dependent prefactor A(r) and depth-dependent activation volume V (super *) (r), energy E (super *) (r), and enthalpy S (super *) (r) can be parameterized using estimates of diffusion constants based on elasticity. (2) Secular changes in Earth's gravity field, particularly the zonal coefficients J (sub l ) are now detected in the orbits of artificial satellites such as LAGEOS and Starlette. These secular changes are believed to be dominated by postglacial rebound, although there is some contribution from present-day glacial melting. These gravity field measurements, when combined with constraints on glacial melting, provide a sensitive set of constraints on lower mantle viscous response to the Last glacial epoch and, hence, provide a test of a priori estimates. A radially stratified and incompressible Earth model is used to test sensitivity of data to viscosity increases with depth and convective boundary layer structure. Prior estimates and observed nontidal J (sub 2) (-C (sub 20) ) are consistent with a layered lower mantle viscosity. Details of this layering are examined by comparing predicted and observed J (sub 3) , J (sub 4) . Speculation that a high-viscosity layer exists above D" is considered. With a 650-km-thick deep high-viscosity layer (eta nearly equal 6.0 X 10 (super 23) Pa s) the remaining lower mantle is in one of two ranges: 1.5 to 3.5 X 10 (super 20) or 3.5 to about 10. X 10 (super 22) Pa s. Observational bounds on secular gravity coefficients C (sub 30) , C (sub 40) , C (sub 50) , and C (sub 70) using LAGEOS, Starlette, or Etalon satellite data could eliminate the ambiguity between these two viscosity ranges.

The California Highway Department (Caltrans) conducted the preearthquake survey in February and March 1989 using single-frequency GPS receivers. In March 1990, we reoccupied eight of the Caltrans stations using dual-frequency receivers. Relative displacements were computed by differencing the station coordinates determined from these two surveys. Displacements were determined relative to sites remote from the earthquake by incorporating GPS measurements from Loma Prieta (station LP1) to the Very Long Baseline Interferometry (VLBI) site at Fort Ord. Examination of repeated measurements in the single frequency preearthquake survey indicates precision is approximately 10 mm in the horizontal, although it may be as low as approximately 40 mm in the weakly connected part of the network. The precision in the Vertical is generally 30-40 mm. In contrast, the largest observed coseismic displacement is 410 mm horizontal and 341 mm vertical. We use a quasi-Newton method to estimate the parameters of the uniform rectangular dislocation source that best fits the observed displacements. The best fitting dislocation dips 68 degrees southwest, extending from 3 to 16 km depth, strikes N66 degrees W, and has 1.8 m of dip slip and 1.2 m of strike slip. The best fitting dislocation overlaps the aftershocks but is rotated 15 degrees counterclockwise from the trend of the afterhock zone. We find that the data can be fit nearly as well with a dislocation that is constrained to lie in the plane of the aftershocks, In this case the fault extends from 5 to 15 km depth. The constrained model explains 96% of the data. Both models have a moment of M (sub 0) = 2.9 X 10 (super 19) N m. We also use the quasi-Newton method to estimate rectangular dislocation models from the leveling data of Marshall et al. (1991), and the trilateration and GPS data of it Lisowski et al. (1990). In contrast to the previous studies, we find that both of these data sets are independently best fit with dislocations embedded within the aftershock zone.

We find that the standard deviation of the twenty-four 2-hourly drop set means taken during a given station occupation is 1-2 mu Gal when natural or man-induced microseismic conditions are low and 3-5 mu Gal when the microseismic activity is high. The standard deviations of the station gravity values obtained by repeated occupations weeks or years apart are within these same ranges, with lower standard deviations found again at bedrock sites where the microseismic noise is low. Based on the repeatability of observations since the beginning of the measurement program in 1987, there is no indication for drift, gradual deterioration, or aging of the instrument. However, because of the degraded performance of the lasers used since 1990, the standard deviation of repeated station occupations increased from 2.27 to 2.87 mu Gal, and data had to be rejected at several sites. Individual station gravity values in excess of + or -3 mu Gal from the station mean are found mostly at those sites where density Variations between reoccupations are expected on the basis of geological conditions, usually due to groundwater table fluctuations and/or soil moisture changes.

Two large earthquakes, the 1944 Tonankai earthquake (M (sub w) =8.1) and the 1946 Nankaido earthquake (M (sub w) =8.3), occurred on the Nankai trough, southwestern Japan, where the Philippine Sea plate is subducting beneath the Eurasian plate. The source areas of these events extended over both land and ocean. Coseismic crustal movements on land were measured by leveling, while those in ocean were recorded as tsunami waveforms on tide gauges. The coseismic slip distribution inverted from these data shows that the slip on the shallower part of the fault plane is comparable to that on the deeper parts. This indicates that large coseismic slip can occur beneath an accretionary wedge where current seismicity is low. The result has implications for other subduction zones having a similar tectonic environment such as for the Pacific Northwest region of the United States. Although the possibility of a large earthquake there is still debated, should a large subduction earthquake occur in this region, coseismic slip on the shallow part could be large, and the potential for large tsunamis is high.

Ground-based GPS estimates of daily and subdaily changes in Earth orientation presently show centimeter-level precision. Comparisons between GPS-estimated Earth rotation variations (UT1-UTC) and those calculated from ocean tide models suggest that observed subdaily variations in Earth rotation are dominated by oceanic tidal effects. Our preliminary GPS estimates for geocenter location (from a 3-week experiment) agree with an independent satellite laser ranging estimates to 10-15 cm. Covariance analysis predicts that temporal resolution of GPS estimates for Earth orientation and geocenter improves significantly when data collected from low Earth-orbiting satellites as well as from ground sites are combined. The low-Earth GPS tracking data enhance the accuracy and resolution for measuring high-frequency global geodynamical signals over time scales less than 1 day. Low-Earth orbiters such as Topex/Poseidon carrying GPS flight receivers will provide opportunities to demonstrate these enhancements. Copyright 1993 by the American Geophysical Union.

The expedition was sponsored by the Intergovernmental Oceanographic Commission (IOC), Regional Organization for the Protection of the Marine Environment (ROPME), United Nations Environmental Programme (UNEP), U.S. National Oceanic and Atmospheric Administration (NOAA), and the Marine Spill Response Corporation (MSRC) and focused on the fate and effects of the 1991 Gulf war oil spills on the region's marine environment. The expedition was unusual, given the limited time in which it was conceived, planned, implemented, and completed. The mission's success may be measured not only in the wealth of scientific data collected, but also in the strides made in local, regional, and international environmental awareness and political cooperation in the Gulf.

Fifteen sharks were caught farther than 50 n.mi. offshore, indicating that tiger sharks do occur well offshore and removed from benthic topography. About 89% of the sharks were caught during October-March, while only 56% of the fishing effort occurred during that period.

Handline fisheries for bottomfish, tuna, and mackerel scad lose bait and catch to bottlenose dolphins, rough-toothed dolphins, and Hawaiian monk seals. Troll fisheries for billfish lose live bait to bottlenose dolphins, rough-toothed dolphins, albatrosses, and boobies; these fisheries may also lose catch to false killer whales. A longline fishery for tuna and billfish has burgeoned in Hawaii since 1987, resulting in interactions with protected species; marine turtles, seabirds, and monk seals take bait and are known to become hooked, and false killer whales may take catch. Research on deterrents or alternative fishing methods has been limited, and interactions have been reduced primarily through management and regulatory actions. These include area closures and gear requirements. An observer program has also been established for the bottomfish and longline fisheries.

The commercial sector has undergone rapid growth in recent years, but recreational and subsistence sectors remain important. Information on these fisheries is generally not available in published form. This paper presents an overview and introduction to a volume of papers describing fisheries in the region, with the goal of making the information available to scientists and the general public. A great deal remains to be learned about the dynamics of these fisheries as well as the associated issues in biological research, fisheries management, and environmental protection.

When mortality (LC sub(50)) was the endpoint, the results indicated that R. abronius was ) 20 times more tolerant to tributyltin than either haustoriid species; however, when mortality plus reburial behavior (EC sub(50)) was assessed, the difference was only about 10 times. The bioconcentration factor (BCF) was also consistently lower in R. abronius (11.1 to 16.5 times) than in the haustoriids; however, when the LD sub(50) was calculated, the concentration in the tissues associated with 50% mortality for each species was not significantly different. An analysis of TBT uptake confirmed that R. abronius was able to accumulate less TBT and hence maintain a low body burden for a given water concentration. Because the rate of TBT uptake was lower in R. abronius, we propose that the slower rise in toxicant body burden allowed for a gradual response in this species which included a sublethal effect (non reburial), compared to a rapid rise in the body burden for E. estuarius which caused the response to quickly proceed from no effect to death.

Relatively little is known about the life history of these species. Research in Hawaii and elsewhere in the tropical Pacific suggests that most of the species are slow growing, long lived, and have a relatively high age at sexual maturity. Stock assessment is difficult because of the multispecies nature of the fishery. However, recent analysis of commercial fishery data indicates that some of the species may currently be overexploited. Research is underway to determine the efficacy of management measures such as minimum-size limit changes or seasonal and spatial fishery closures to maintain optimal spawning biomass.

Ichthyoplankton surveys are routinely conducted by the National Marine Fisheries Service in Shelikof Strait during peak spawning time of walleye pollock. Survey data from 1981 and from 1985 to 1988 were used in this analysis. The annual production of eggs was estimated in two steps. First, the average spawning season was described by a unimodal curve relating egg production to date within the season. This was estimated by regressing daily production of young eggs from each cruise against the mean date of the cruise. Only those years with multiple cruises during the spawning season were used to estimate parameters of the annual egg production curve. Peak spawning was found to occur between 15 March and 2 May. Next, egg mortality and annual egg production were estimated by integrating a model over the spawning season that combines the annual egg production curve with an exponential mortality model. Annual egg production appears to have declined since the highest level in 1981. Annual fecundity per gram female varied over years. Sex ratio was assumed to be 0.5 in numbers of fish, but it was scaled to average male and female weights. The resulting spawning biomass estimates follow the same downward trend as the annual egg production estimates and follow the same trend as biomass estimates for walleye pollock based on other methods and surveys.

This idea, first proposed by Hensen and Apstein (1897), has led to the development of ichthyoplankton methods currently used around the world to estimate biomass, and monitor trends in fish abundance. In recent years, ichthyoplankton based approaches have become more important because of increased demands for fishery-independent information. Five ichthyoplankton based methods for biomass estimation were described in this symposium: annual egg production method (AEPM), annual larval production method (ALPM), daily egg production method (DEPM), daily fecundity reduction method (DFRM), and egg deposition method (EDM). A variety of inexpensive ichthyoplankton indices of fish abundance was also described. JF - Bulletin of Marine Science [BULL. MAR. SCI.]. Vol. 53, no. 2. 1993.

The boundary was determined by satellite images of the Loop Current and the ship was positioned to make a transect across the boundary whenever it approached a boundary during its normal survey operations. Eight transects were made and the composition and abundance of the fish larvae were determined for each tow. Eight to 10 ten tows were made at 2- to 4-km intervals. Taxonomic diversity of the ichthyoplankton was higher than previously reported for the Gulf of Mexico or Caribbean (100 families). Cluster analysis of families produced two major groups, oceanic and continental, but our hypothesized frontal assemblage is not coequal with the oceanic and shelf groups. Cluster analysis of stations also supported the hypothesis of contrasting oceanic and shelf assemblages. Principal-components analysis found more than one-half of the variance in the data to be summarized by three independent patterns. The high diversity of larval fishes is due to the mix of faunas from tropical and warm temperate oceanic, mesopelagic, and coastal demersal and pelagic species which is enhanced by the dynamics of the oceanographic system of the Loop Current.

Recurrent group analysis of 249 larval fish taxa placed 36 taxa in 12 recurrent groups. These groups reflect the oceanographic complexity of the region with Subarctic-Transitional, Eastern Tropical Pacific (ETP), and Central Water Mass components. The major shorefish recurrent group is associated with the large shelf area of Sebastian Viscaino Bay off central Baja California. Cluster analysis using correlation coefficients of abundance as the measure of distance and principal component analysis produced groupings that agreed in general with groups formed by presence-absence analysis. Environmental effects on these groups were studied by examining changes in horizontal and vertical distribution across a frontal region. Plankton samples from the FRONTS 85 cruise conducted in July, 1985, southwest of the Southern California Bight, allowed us to investigate the fine scale distribution of assemblages across a semi-permanent frontal zone separating cold eutrophic water to the north from relatively warm, oligotrophic water to the south. Ichthyoplankton samples from a 120-n. mi. transect across the front, including 42 oblique bongo tows and 8 MOCNESS tows to 1,000 m, demonstrated: 1) the transition between Subarctic-Transitional and ETP/Central Water Mass species, and 2) distinctly different patterns of vertical distribution for the same species at the north and south sides of the front.

This method was developed for estimating adult biomass of fishes with determinate annual fecundity and utilizes the daily decline in reproductive potential of the population and the numbers of planktonic eggs. Daily decline in reproductive potential was estimated from the decline of the product of the standing stock of advanced oocytes and the numbers of females with reproductively active ovaries. Daily production of planktonic eggs was estimated from the numbers of eggs in quantitative oblique plankton tows. We describe the survey design, data assembly, statistical estimation procedures, and the possible biases due to the limitation of surveys. JF - Bulletin of Marine Science [BULL. MAR. SCI.].

Year-to-year variation of recruitment rate may be of the same order of magnitude as measurement uncertainty and population changes may have to be sustained for 2 to 3 years to be detectable using the precision available from current techniques. As fishing rates accelerate, the dependence of the fishable biomass on recruitment is increased. Pre-recruit survival and growth may be more episodic than adult survival and fecundity (Smith and Moser, 1988). The episodic nature of recruitment combined with higher fishing rates may make more frequent biomass estimates necessary. When variable recruitment and high total instantaneous mortality rates (ITMR) reach a certain level, effective fisheries management will require development of recruitment prediction procedures in addition to virtual population and biomass monitoring. Annual biomass surveys may be redundant because many stocks contain several year classes. The costs of implementing recruitment prediction and systems to monitor biomass may be a significant fraction of the value of the added catch and this should be considered during management planning.

Alternatively, we derived a fishery independent index of western Atlantic stock size from ichthyoplankton surveys conducted by the National Marine Fisheries Service. The larval abundance indices developed from these surveys have been used to corroborate trends in fishery dependent estimates of stock size, as well as to tune the virtual population analysis. Estimates of average annual larval abundance at first daily increment formation per 100 m super(2) sampled by oblique bongo tows were used to index total annual larval abundance. A model describing the observed mean trend in larva size at otolith daily increment count was developed to estimate a probability of age at length matrix for ageing the captured larvae. Daily loss rates (Z) were estimated through regression analysis of the larval catch curves. Effects of mesh size changes (333 mu m or 505 mu m) during the time series of sampling were incorporated into the estimates. Uncertainty in the index values for the various components of the estimator is incorporated through the delta method. Zero catch information from the sampling is incorporated through application of Pennington's transform. Finally, we tested several different methods of calculating the index to evaluate the sensitivity of the results to different assumptions. JF - Bulletin of Marine Science [BULL. MAR. SCI.].

There is exchange of water across frontal zones and, as a consequence, there is flux of biota. The spatial distribution of larval gulf and Atlantic menhaden (Brevoortia patronus and B. tyrannus), and spot (Leiostomus xanthurus), presumed indicators of larval fish assemblages in and about two well defined, but vastly different frontal zones, serve as examples of the flux of larval fishes across water-mass boundaries. Across the Mississippi River plume front in the Gulf of Mexico and the western Gulf Stream front in the southeastern Atlantic bight of the United States, mixing and stirring can account for flux of larval fishes. The consequences of flux for the larvae of these indicator species is their shoreward transport, or the reciprocal, their expatriation from coastal populations. JF - Bulletin of Marine Science [BULL.

For an agency such as NOAA, the most effective form of support to the education community would be improved access to data and information. The NOAA-NODDS system provides that improved access by making available to schools a system that allows teachers to access the latest environmental information for anywhere in the world for the cost of a telephone call. Two years ago the Navy introduced a new generation of NODDS. The new system uses a PC for the users workstation and regular telephone lines for the communications. The user can SELECT AREA's of interest for anywhere in the world and SELECT PRODUCTS from a menu. These steps can be done in advance, and for as many areas of interest as desired, and the information retained in the workstation. When the user desires, he selects the RETRIEVAL function and the PC makes a phone call to Monterey, connects to the data base server, downloads the data and hangs up the phone. All this takes a couple of minutes. The user then has the choices of using a variety of DISPLAY options, saving the data with the ARCHIVE function or porting the data to other applications programs. The system is very flexible, very easy to use, runs on simple computers, and uses normal telephone communications. Data available includes ocean and atmospheric observations, satellite images and computer produced ocean and atmospheric analyses and predictions. JF - PROC. MAR. TECHNOL. SOC.

Early ichthyoplankton studies focused on the geography and timing of spawning and the survival of the young of commercially important species, while the collections of far ranging oceanographic expeditions provided a global view of ichthyoplankton diversity and distribution patterns. The utility of ichthyoplankton approaches in fisheries research has increased in response to an increasing need for fishery-independent stock assessment, the subject of the companion symposium in this volume. With fisheries science now moving beyond single-species concepts, ichthyoplankton research has a key role in our understanding of the ecology and evolution of fish faunas and their constituent populations. The need to focus on ichthyoplankton assemblages as an integral part of their environment is central to this understanding and is the basis for this symposium. JF - Bulletin of Marine Science [BULL.

Plume centreline simulation is performed by numerically tracking marked particles released continuously from an outfall diffuser, provided that current fields are known either from current meter data or numerical modelling. The contaminant concentration field at any time is estimated from a deterministic diffusion model which applies to plume segments along the centreline at that time. The centreline and concentration field simulations are continued over time (known as simulation time); visitation frequency at any point is obtained by accumulating the time interval during which the concentration at this point exceeds a specified value and from the ratio of the accumulated time to the simulation time. The method presented was applied to a case study of the proposed Heishijiao Bay Outfall, Dalian, China. In this case study, total coliform was taken as a pollution indicator in the estimation of visitation frequency. A comparison was also made of our method with Churchill's plume simulation method; good agreement between two methods was achieved.

However, very little is known about the population size, stock structure or movements of these sharks in the northern Pacific. It is important to determine their role in these waters because the southern California bight may be an important pupping and nursery area for shortfin mako sharks. Acoustic telemetry was used to identify short-term horizontal and vertical movements of three shortfin mako sharks in the southern California bight during the summer of 1989. All three sharks were two-year-old juveniles and were tracked for periods of from 18 to 25 h. They spent 90% of their time in the mixed layer, with only infrequent excursions below the thermocline. Vertical and horizontal movements did not indicate any diel activity pattern associated with distance to the shore or nearby islands or with bottom topography.

In all tests, the LC sub(50) decreased 2 to 3-fold for animals held for several weeks in the laboratory versus those recently collected from the field. Additionally, the LD sub(50) for both toxicants was also 2 to 3 times lower for both species of laboratory-maintained animals. For both species, whole-body lipids declined by a factor of 2 to 3 during the holding period and when the LD sub(50) for each toxicant was lipid normalized, the critical body burdens became nearly the same. Because TBT is a lipophilic compound, it is expected to partition according to organismal body lipid, however, Cd is known to not partition preferentially to lipid. It is possible that declining lipid concentrations may be the mechanistic process by which body burdens of TBT are controlled, but for Cd, another mechanism may be more important. It was concluded from these results that decreasing whole-body lipid content may be an indicator of declining animal health (and increased sensitivity to toxicants) but the actual mechanistic control over the toxicity response remains to be elucidated. It is assumed that the standard 10-day test, conducted with recently caught animals, probably has no impact on organism health, but that caution should be used when interpreting bioassay results from long-term studies that use animals which are not maintained in optimum condition. This study also suggests that variability in response to toxicants may occur over the natural, seasonal cycle of physiological variation that occurs in populations.

Pups were double flipper tagged as soon as possible post-weaning. With few exceptions, an extensive tag resighting effort was conducted annually at the same islands. These resighting data were used to estimate seal survival rates from the time of tagging to age one at all locations using the ratio of seals alive in the second year to number of pups tagged. These survival rates among the islands, from weaning to age one, averaged over the years of the study, ranged from 0.80 to 0.90. For young seals over age one, capture-recapture methods were used to calculate survival pooled through several years, and these rates ranged from 0.85 to 0.98. At French Frigate Shoals and Laysan Island, the higher numbers of tagged pups allowed separate estimates of male and female survival to be calculated. These rates suggeted that survival of immature females was better than males. Beginning in 1989, survival of immature seals at French Frigate Shoals declined sharply.

MNPL/K is used in management of marine mammals but no empirical evidence exists to limit the range of values expected. Density dependent changes in age-specific birth and death rates have been used to infer MNPL/K. Non-linearities in these rates do not translate directly to population growth curves. The simple models demonstrate: density dependence is likely to involve more than a single parameter (such as birth rate), MNPL/K can be greatly reduced from that inferred from one strongly non-linear parameter when changes in other parameters are linear, ranges of MNPL/K depend on biological limits on ranges of fecundity and survival rates, and the magnitude and sign of bias incurred by inferring MNPL/K from functional forms of single parameters cannot be determined. Given current empirical evidence the range of MNPL/K for marine mammals as a group is large. Although MNPL/K should not be inferred from single parameter non-linearities, distributions of MNPL/K values can be generated through models which account for single species ranges for birth and death rates and maximum population growth rate.

Two surveys of the area of larval distribution were done 12 d apart and daily mortality rates estimated from changes in abundance of each cohort. This study was designed to minimize potential sources of bias to mortality estimates, such as larval extrusion or escapement from sampling gear, advective or diffusive gain or loss of larvae into or out of the sampling area, the uncertainty incurred by the use of length as a proxy for age, and the often erroneous assumption of constant production and mortality rates. The age-specific mortality rates from this study were low compared to rates previously estimated for larval walleye pollock. Four significant mortality estimates, ranging from 0.041 to 0.076/d, came from among the youngest cohorts. The low larval mortality rates in 1988 coincided with very calm ocean conditions. Larval drift rates estimated in this study were coherent with the movement of a satellite-tracked drift buoy and averaged 3.1 to 3.9 cm/s, which is comparable to rates reported from other studies.

Large marine ecosystems (LMEs) have been described as regional units for the conservation and management of living marine resources in accordance with the legal mandates of UNCLOS. The principal forces driving large-scale changes in living marine resources vary among LMEs. Progress in the research and management of living marine resources and their biomass yields can be enhanced by comparing the multiple stable states among LMEs with regard to the causes of stress or perturbation on the system and the feedback of the system to stress. The results of recent meetings and workshops leading to the characterization of 49 LMEs are given, along with a discussion of a "core" monitoring strategy for LMEs. JF - IST. SCI.

AN - 16664365; 3021700 AB - Gymnodinium breve (= Ptychodiscus brevis ) frequently forms red tide blooms off the west coast of Florida. Historical records indicate occurrences off Florida dating back to 1844, and, less frequently, elsewhere around the Gulf of Mexico and Caribbean basin. Our understanding of the processes contributing to these blooms is hampered by a lack of information on background levels of G. breve throughout the year and throughout the basin. The NOAA fleet has extensive capabilities to take surface water samples while underway; but we needed to evaluate the validity of a surface-only sampling strategy. Estimates of G. breve cell abundance in the northern Gulf of Mexico based on 61 stations sampled at depths of 0 to > 150 m during three cruises tested the hypothesis that cells were more abundant near the surface. In shallow, well-mixed areas G. breve was evenly distributed with depth; however, at deeper stations having thermoclines, G. breve was more abundant near the surface. In the central Gulf of Mexico, G. breve occurred year-round at concentrations of < 10 cells/L. Cell concentrations were generally greater at coastal stations, where the greatest concentrations were counted (100 cells/L). JF - DEV. MAR. BIOL. 1993.

AN - 16633488; 3021730 AB - Since 1989, paralytic shellfish toxins have been detected in shellfish from the American sector of Georges Bank at levels exceeding the public health safety threshold, necessitating closure of shellfisheries in these offshore waters for the first time. The toxins reached maximum levels in offshore shellfish during the summer of 1990, but have persisted at lower levels, still exceeding the safety threshold, in some species. Maximum toxin levels in whole animals, determined by mouse bioassay, were 6400 mu g STX equiv./100 g tissue for Atlantic surfclams (Spisula solidissima ), 3900 mu g STX equiv./100 g tissue for sea scallops (Placopecten magellanicus ), 3600 mu g STX equiv./100 g tissue for northern horsemussels (Modiolus modiolus ), and 1200 mu g STX equiv/100 g tissue for ocean quahogs (Arctica islandica ). High toxin levels have also been detected in carnivorous molluscs such as northern moonsnails (Euspira heros ) and waved whelks (Buccinum undatum ). In May and June 1990, eight fishermen were poisoned after eating blue mussels (Mytilus edulis ) taken as bycatch from Georges Bank; in the Jun incident the mussels contained more than 24000 mu g STX equiv./100 g tissue before cooking. The source of the offshore toxins is presumed to be the dinoflagellate Alexandrium tamarense , which causes shellfish toxicity annually in the inshore waters of New England and eastern Canada, although blooms of A. tamarense have not been confirmed in the Georges Bank area. The occurrence of high levels of toxins in offshore shellfish is apparently a new event and raises scientific questions as well as fisheries and public health management issues. JF - DEV. MAR.

Post-set juvenile hard clams and bay scallops, Argopecten irradians , were maintained in flowing seawater from which nutritionally-useful particles were filtered, and mollusks were fed axenically-cultured phytoplankton. Feeding treatments included: (A) unialgal P. micans , (B and C) P. micans mixed in two percentages with a standard bivalve food (Isochrysis sp., T-ISO, (D) P. minimum mixed with T-ISO, (E) T-ISO alone, and (U) unfed controls. Clams filtered all algal diets and, after ten weeks, survived well in all feeding treatments. Growth of clams was similar and relatively rapid on the three diets which included T-ISO, and mediocre on P. micans alone; however, clams fed mixed T-ISO/P. minimum did not grow. No algal diets supported good, consistent growth of scallops; nevertheless, survival results demonstrate clear differences between feeding treatments. JF - DEV. MAR. BIOL. 1993.

AN - 16588254; 3021774 AB - Transport of Gymnodinium breve (= Ptychodiscus brevis ) cells in the Gulf Stream was implicated in an unusual North Carolina red tide bloom in 1987-1988. One of the most compelling questions which resulted was: are Gymnodinium breve cells transported from the Gulf of Mexico into the South Atlantic Bight (26 degree N, 80 degree W to 35 degree N, 75 degree 30'W) continuously by the Florida Current - Gulf Stream System? Since 1988, water samples collected throughout the South Atlantic Bight and the northern Gulf of Mexico by vessels of the NOAA fleet ("ships of opportunity") have helped provide answers to this and other questions. Preliminary results of this ongoing work are discussed in relation to the transport processes along the west Florida shelf, the Florida Current - Gulf Stream system, and the potential effects of global warming.

AN - 16489657; 2938851 AB - The vertical distribution of pelagic juvenile stages of fish can be altered by a variety of environmental stimuli. In laboratory experiments, we tested the influence of light intensity, thermal stratification, and predator presence on vertical distribution in juvenile walleye pollock (Theragra chalcogramma Pallas). In addition, we measured activity levels and group cohesion (schooling tendency). Experiments were conducted over a broad size range (37-126 mm), allowing us to test for ontogenetic variability in behavioral responses. Juvenile pollock displayed distinct responses to predator presence and thermal stratification, shifting downward and upward, respectively, relative to their average vertical position under baseline experimental conditions. When pollock were exposed to the two conflicting stimuli of a stratified water column plus a predator, their average depth was midway between the mean positions observed with each stimulus alone. The fishes response to bright light was less clear. Increased light levels did not significantly alter the average vertical position of pollock in the water column, but did result in increased use of the cold water layer under stratified conditions. There was an ontogenetic shift in pollock behavior. Smaller fish were less active, had a smaller range of movement through the experimental tank, and were less likely to dive through the thermocline in a stratified water column. Smaller fish also demonstrated less group cohesion, having a lower tendency to aggregate or school compared with larger fish. These behavior patterns are potentially useful in explaining distribution patterns of juvenile Walleye pollock in the field.

AN - 16404353; 2883216 AB - In this study, we demonstrate that video records with altitude, pitch, and roll problems that are not useful for density estimates can be enumerated using species-time techniques. We compared the strip transect method with two species-time census methods: rapid visual technique (RVT) and visual fast count (VFC). Comparisons were made using data from an actual series of video transects and a simulation. The simulation study was used to assess the performance of the three census methods under conditions of variable field-of-view. The VFC method produced estimates of relative abundance that were not significantly different from strip transect estimates or true values of relative abundance. Results using the RVT method were significantly different from the strip transect and true values in most cases. Individual transects were treated as true replicates and not lumped to reduce variation. Relatively large sample sizes were needed to compare abundances of rare species.

In instances involving illegal possessions, in cases of single or mass strandings, or in the collection of life history data, one of the most important components is the determination of the natal origin of juvenile and adult turtles. An analysis of the genetic information of loggerhead turtles suggests they follow natal homing behavior similar to green turtles. Therefore, nesting populations of loggerheads should be managed as "demographically independent units". If nesting females are depleted or reduced at a particular locale, the dispersal rate from other regions may not be sufficiently rapid to restock the original population over a timescale that can be meaningful and adequately controlled by wildlife management agencies. By analyzing mitochondrial DNA (mtdna) it is possible to look at migratory behavior and determine population structures of female loggerheads (Bowen et al. 1992).

On the other hand, the diet of hawksbill turtles within the shallow coastal waters of Panama, Lesser Antilles and Hispaniola appears to feed quite specifically on marine sponges (Meylan, 1984, 1988). There is very little information on the feeding habits of hawksbill turtles on the Puerto Rican shelf (Vicente and Carballeira, 1992). This study provides information on the gut contents of 11 stranded specimens of E. imbricata found within the coastal waters of Puerto Rico and of the U.S. Virgin Islands.

Numerous sightings of sea turtles reported by NMFS personnel and by the general public through a sea turtle sighting campaign led to the hypothesis that the jetties and associated channel of Brazos Santiago Pass could be important developmental habitats for sea turtles (Williams and Manzella, 1992). Unfortunately, turtles in these areas could potentially be impacted by dredging activities in the channels. On the Atlantic coast of the United Sates there have been documented injuries and mortalities of sea turtles from the use of hopper dredges (Dickerson et al, 1991).

The NMFS portion of the study is discussed here. Nine turtles were fitted with sonic and backpack radio transmitters. Two of these were given trailing floats containing a time-depth recorder. A tenth turtle was given only a sonic transmitter. Releases were at point of capture. Monitoring from boat and land averaged 9-10 hours per day. Observation data were grouped into the categories dawn (05:00-09:00), day (09:00-17:00), dusk (17:00-21:00), and night (21:00-05:00) for analysis. Eight turtles remained near the jetty area throughout the study period. These turtles generally stayed within 10 m of the rocks. Total study period movements along jetties ranged from less than 370 m to over 1200 m. Core a eas (areas containing greater than or equal to 50% of observation time) ranged from 46 to 275 m and often varied by time of day. The channel was seldom used, with most use by the two largest turtles. Analysis of surface/submerged times indicate that dive intervals shorten during early morning and evening, and are longest at night. Results appear to demonstrate that these turtles have at least short-term range fidelity, have very little use of the channel, and are most active at dawn/dusk and least active at night.

Distinct profiles were found for each of the species examined. Species identification, based on fatty acid composition, have been instrumental in successful prosecution of several egg poaching cased in South Carolina, Florida, and the US Virgin Islands. A computer database of fatty acid profiles has been established and currently contains compositions for 205 eggs, oils, depot fats, and muscle. These profiles include fatty acids biosynthesized by the animal as well as those from direct incorporation of dietary fatty acids. In addition to characterizing the animal, the profiles provide information on dietary components of the various species and feeding habits prior to nesting. Information is continually added as samples become available. Several cooperative projects have also been initiated with other marine turtle researchers to explore the potential of fatty acid compositions to indicate turtles' diets and the possibility that the females may be deficient of essential fatty acids at nesting time.

ER - TY - RPRT T1 - INTERIM COLUMBIA AND SNAKE RIVER FLOW IMPROVEMENT MEASURES FOR SALMON; OREGON, WASHINGTON, AND IDAHO (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JANUARY 1992). AN - 36409528; 3977 AB - PURPOSE: The modification of flow regimes associated with eight projects on the Columbia River and its tributaries in Idaho, Oregon, and Washington is proposed in order to improve the Pacific salmon fishery. The Columbia River and its tributaries form the dominant water system in the Pacific Northwest. The geographic scope of this analysis is the Columbia River Basin from the Bonneville Dam in Oregon upstream to Brownlee Reservoir on the middle Snake River in Idaho, and farther upstream to Arrow Lakes on the upper Columbia River in Canada. The water management actions under consideration would be implemented at three storage reservoirs (Dworshak, Grand Coulee, and Brownlee) and five mainstream run-of-river dams operated by the Corps of Engineers. The dams are operated to meet multiple purposes, including navigation, flood control, hydropower, recreation, irrigation, and fish and wildlife habitat. This final supplement to the final EIS of January 1992 responds to two actions of the National Marine Fisheries Service (NMFS): in November 1991, NMFS declared the Snake River sockeye salmon an endangered species, and in April 1992, NMFS listed the Snake River fall and spring /summer chinook salmon as a threatened species. In taking these actions, NMFS identified hydropower development within the Columbia River Basin as one of the factors contributing to the decline of salmon populations. The final EIS had recommended increasing the velocity of river flow to move the juvenile salmon downstream more rapidly and reduce their exposure to predators, but the scope of that EIS was limited to actions to be implemented in 1992. This final supplement considers the implementation of flow improvement measures for 1993 and subsequent years. Five alternatives, including a No Action Alternative, are considered in the final supplement. Under the preferred alternative (Alternative 4), most actions occurring during the 1992 operating year would be recommended for 1993 and thereafter, except for the March drawdown test. These actions include lowering pool elevations at the affected reservoirs during all or part of the smolt migration, and discharging additional water during the spring migration season to increase river flow. Volumes to be discharged under the Snake River flow augmentation plan include 900,000 acre-feet (af) in the spring (if the runoff forecast is above 16 million af; otherwise one million af) and 470,000 af in the summer from Dworshak; 137,000 af in July and 100,000 af in September from Brownlee; and 190,000 af in the spring, 137,000 af in August, and 100,000 af in September from the upper Snake River. Under the Columbia River flow augmentation plan, up to three million af would be discharged from Grand Coulee and the upper Columbia River. The estimated direct costs for the operation of the preferred alternative range from $66 million to $93 million. POSITIVE IMPACTS: By increasing flows for upstream and downstream migration, the plan would improve the ability of salmon populations to spawn and migrate within the Columbia River system. As a result, populations could increase significantly. NEGATIVE IMPACTS: Drawdown of the reservoirs would have an adverse effect on resident fish populations. The lowered pool elevations and flow augmentation actions would result in lost hydroelectric generation and operating flexibility, which in turn would probably result in the necessity of purchasing some power from outside the region. The exposure of reservoir shorelines as a result of drawdowns would detract from their aesthetic quality. LEGAL MANDATES: Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.).

The roughness density is quantified by the frontal area index lambda . The prediction is R (sub t ) = (1 - msigma lambda ) (super -1/2) (1 + mbeta lambda ) (super -1/2) , where beta is the ratio of the drag coefficient of an isolated roughness element on the surface to the drag coefficient of the substrate surface itself; sigma is the basal-to-frontal area ratio of the roughness elements; and m (< 1) is a parameter accounting for differences between the average substrate surface stress and the maximum stress on the surface at any one point. The prediction is well verified by four independent data sets. Copyright 1993 by the American Geophysical Union.

The decline of the fishery appeared to be driven largely by opportunity costs, which, in turn, depended on the ethnic background of crew members. Our analysis indicated that opportunity costs and sociological factors, which are often ignored by fishery managers who traditionally focus on biological analyses, can affect a fishery and its performance. Estimates of opportunity and variable costs from our study should be useful in the development of management plans for the wetfish fishery.

Major factors in these dynamics are: (1) the overturning of seawater that occurs in the Atlantic but not the Pacific Ocean, (2) th e constriction of oceanic circulation imposed by the Drake Passage between South America and Antarctica, (3) various aspects of tropospheric dynamics, and (4) the stratospheric cooling that is anticipated as a result of an increase in atmospheric carbon dioxide. Predictions are being made about the sensitivity of the circulation of the Atlantic Ocean to increasing freshwater input at high latitudes; the possibility of greenhouse cooling in the southern oceans; the sensitivity of monsoonal circulations to differential warming of the two hemispheres; the response of mid-latitude storms to changing temperature gradients and increasing water vapor in the atmosphere; and the possible importance of positive feedback between the mean winds and eddy-induced heating in the polar stratosphere. Comprehensive numerical climate models will continue to play a central role in this field, and the analysis of a hierarchy of simpler models will be needed to help develop confidence in the robustness of p redicted responses, as well as to develop rational strategies for analyzing and comparing the predictions of various comprehensive models. The challenge will be to find those key observations, whether in paleoclimatic records or in the interannual variability of the atmosphere and oceans, or in the first hints of the structure of the greenhouse warming itself, that can be used to constrain or verify the models in relevant ways.

In August 1990, the Navy declassified all Geodetic Mission (GM) data that lie south of 60 degrees S, and in 1992 declassified all data that lie south of 30 degrees S. Fine-scale tectonic features of much of the world's seafloor could be viewed for the first time. The Southwest Indian Ri dge (SWIR) was used to demonstrate the information contained in gravity fields derived from the Geostat GM sea-surface height data. The SWIR is a mid-ocean ridge along which seafloor spreading occurs between the African and Antarctic plates at a rate of 16 mm/year since Oligocene times. In addition to fracture zones associated with the SWIR, there are traces of older fracture zones on the seafloor. A complicated opening of the Indian Ocean is indicated in the high-resolution gravity fields that cover the SWIR. A more precise history of the relative motion between the African, Indian and Antarctic plates will be determined by modeling past plate motions, examining these newly revealed seafloor features, and using other geophysical information such as magnetic anomalies. The geophysical community will ultimately require high- resolution altimetry for the oceans of the entire world. Altimeter data to be collected by the European Space Agency's ERS-1 satellite should meet this requirement. Altimeter data will be collected along densely spaced ground tracks that span the entire ocean. (Brunone-PTT) JF - EOS EOSTAJ, Vol. 74, No. 8, p 86-87, February 23, 1993. 1 fig, 4 ref.

AN - 36413517; 3938 AB - PURPOSE: The establishment of the Delaware National Estuarine Research Reserve, and the designation of two sites as its components, is proposed. The National Estuarine Research Reserve System, originally called the National Estuarine Sanctuary Program, is a federal-state cooperative venture. Federal matching grants are available to coastal states for the development and management of a national system of estuarine research reserves that are representative of the various regions and estuarine types in the US. Federal financial assistance for development, operation, and management of the Delaware reserve has been requested by the state. The reserve would be representative of the diversity of ecosystems found in the Middle Atlantic Subregion of the Virginia Biogeographic Region. The Middle Atlantic Subregion extends from Sandy Hook, at the New York /New Jersey line, to Cape Hatteras, at the Virginia/North Carolina line. The two sites under consideration, which are associated with Delaware's Lower Saint Jones River and Blackbird Creek, cover a total of 4,000 acres of land and water. The Lower Saint Jones River estuary would serve as the focal component of the reserve. The reserve would be used primarily for education and research purposes, particularly as a tool for improving coastal decision making. Traditional uses within the boundaries of the reserve would continue to be regulated by existing local and state laws and site owner policies. Fish and wildlife scientists would be brought together with other environmental scientists, educators, and managers to operate their estuarine and coastal management programs from an education and research center located on the reserve. A collaborative management approach would be implemented, involving advisory committees, landowners, private organizations, and local, state, and federal agencies. Reserve staff would include a program manager, an estuarine educator, a coastal program specialist, and a clerical worker. Other staff could include a research coordinator, an education coordinator, a volunteer coordinator, a research protection specialist, a cultural preservation specialist, a folklorist, an aquatic coordinator, and visiting researchers. In addition, there would be a major committee composed of representatives of agencies and organizations that have an interest in the programs of the reserve; this committee would serve the reserve in an advisory capacity on matters concerning resource protection, education, research, and monitoring. POSITIVE IMPACTS: The educational program of the proposed reserve would increase public awareness of the estuarine resources of the Middle Atlantic Subregion, and their importance. A research plan associated with the reserve would establish a baseline monitoring program for the estuarine areas represented by the two reserve components, and would encourage research projects consistent with the reserve's role as a protected natural field laboratory. NEGATIVE IMPACTS: The construction of the education and research center would result in some surface disruptions and short-term water quality degradation; the site for the center would be adjacent to wetlands and woodland fringe. Increased numbers of visitors to the area would increase the risk of human disruption to the area. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.).

AN - 75516636; 8416801 AB - For understanding of the role of oxidative DNA damage in biological processes such as mutagenesis and carcinogenesis, it is essential to identify and quantify this type of DNA damage in cells. This can be achieved by gas chromatography/mass spectrometry. The present study describes the quantification of modified bases in DNA by isotope-dilution mass spectrometry with the use of stable isotope-labeled analogues as internal standards. A number of isotopically labeled DNA bases were synthesized. The mass spectra of their trimethylsilyl derivatives were recorded. Calibration plots were obtained for known quantities of modified bases and their isotope-labeled analogues. Quantification of various modified DNA bases by isotope-dilution mass spectrometry was demonstrated in isolated chromatin exposed to ionizing radiation. The results indicate that gas chromatography/stable isotope-dilution mass spectrometry is an ideally suited technique for selective and sensitive quantification of modified bases in DNA.

AN - 75903918; 8357346 AB - This paper presents material which is intended to assist researchers in identifying and controlling a range of biological, electrical, and other physical parameters that can affect the outcome of in vitro studies with extremely low frequency (ELF) magnetic and electric fields. Brief descriptions of power line magnetic and electric fields are provided and methods for the generation of 60 Hz as well as other ELF fields in the laboratory are surveyed. Methods for calculating and measuring exposure parameters in culture medium are also described. Relating in vitro and internal in vivo exposure conditions across different animal species is discussed to aid researchers in selecting levels of field exposure. The text is purposely elementary, and sometimes brief, with references provided to aid the interested reader in obtaining a fuller understanding of the many topics. Because the range of experimental parameters that can influence the outcome of in vitro studies with ELF fields is so broad, a multidisciplinary approach is normally required to carry out the research.

Most data are presented at the national level, and selected data are shown for the 10 states with the largest Hispanic American population in 1990 and the 10 states with the largest number of Hispanic American-owned firms in 1987. The 1990 census showed that 22,354,059 persons identified themselves as being of Hispanic origin, a 53 percent increase since 1980. This growth has resulted from natural increase and substantial immigration from Mexico and Latin America, and the Census Bureau expects the Hispanic American population to continue to grow well into the next century. Data are presented in 57 figures.

Components of a sociology of finance would include: (1) the level of the decisionmaker; (2) the societal level receiving the impact of the decisions; & (3) the respective purviews of decision making by level -- eg, budget allocations & tax matters at the governmental level, employee benefits policies & lending policies at the organizational level, & spending or saving matters at the family or individual level. Tax policy is placed in the framework to demonstrate the conceptual territories that could readily be claimed by a sociology of finance, accelerating the reemergence of economic sociology.

All core subsamples were analyzed to determine bulk chemistry and selected subsamples were analyzed for trace-element partitioning and (137)Cs activity. The purpose of these analyses was to determine the trace-element concentrations and distributions in the sediment column and to try to establish a trace-element geochemical history of the lake in relation to mining and mining-related discharge operations in the area. Substantial portions of the near-surface sediments in Lake Coeur d'Alene are markedly enriched in Ag, As, Cd, Hg, Pb, Sb, and Zn, and somewhat enriched in Cu, Fe, and Mn. Variations in the thickness of the trace element- rich sediments suggest that the source of much of this material is the Coeur d'Alene River. Calculated estimates indicate that there are some 75 million metric tons of trace element-rich sediments currently on/in the lakebed. Estimated trace-element masses in excess of those caused by non-mining-related sources, range from a high of 468,000 metric tons of Pb to a low of 260 metric tons of Hg. The similarity between the trace element-rich surface and subsurface sediments as regards their: (1) location; (2) bulk chemistry; (3) interelement relationships; and (4) trace-element partitioning indicate that the sources and/or concentrating mechanisms causing the trace-element enrichment in the lake probably have been the same throughout their depositional history. Based on Mt. St. Helens' ash layer from the 1980 eruption, ages estimated from (137)Cs activity, and the presence of 80 discernible and presumably annual layers in a core collected near the Coeur d'Alene River delta, it appears that deposition rates for the trace element-rich sediments varied from 2.1 to 1.3 cm/yr. These data also indicate that the deposition of trace element-rich sediments began, at least in the Coeur d'Alene River delta, sometime between 1895 and 1910, dates consistent with the onset of mining and ore-processing activities in the area which began in the 1880's.

High resolution (well-dated) dust records from both polar ice sheets suggest a linkage between increased atmospheric dust and cooler temperatures over Antarctica, but a similar relationship is not observed in ice cores from either Greenland or China. Net accumulation histories for the last 490 years reveal no discernible global pattern, although interesting regional differences and similarities exist. (Auth.)

The time to evacuate a number of people using one group of elevators includes the sum of all the round trip times divided by the number of elevators plus the times needed to start up the elevator evacuation and to travel from the elevator lobby to the outside or to another safe location. A trip inefficiency is used to account for trips to empty floors and trips to pick up a few stragglers. The method includes detailed analysis of elevator car travel including constant acceleration, transitional acceleration, constant velocity, transitional deceleration, constant deceleration, and leveling. The time for people to enter and exit the elevator car is addressed including inefficiencies for elevator door sizes and types. The impact of elevator arrangements is addressed, and the difference between commonly accepted and unusual arrangements is presented. A computer program, ELVAC, was written to calculate elevator evacuation time, and an example calculation of evacuation time is provided using this program.

Epinephrine [E] was not detected in most of these invertebrates. A high performance liquid chromatographic procedure was modified for use with aquatic invertebrates. Chironomids and oligochaetes contained D concentrations that were similar, averaging 1 pmole/mg wet wt. Crustacean D levels were lower, averaging 0.2 pmole/mg wet wt. NE averaged 0.2 pmole/mg wet wt. Ror chironomids and 0.57 pmole/mg wet wt. Ror oligochaetes. NE was not detected in the crustaceans. Individual chironomids contained detectable levels of catecholamines; all other invertebrates required pooled homogenates. The chironomid group was targeted for laboratory stress experiments. Cultured midge larvae (Chironomus tentans) subjected to acute thermal stress (35 degree C) exhibited D concentrations significantly lower than controls (23 degree C). Animals exposed to lindane concentrations 0.5 mg/L - 8.0 mg/L contained D concentrations significantly higher than controls. NE and E were not detected in either stress experiment. Demonstration of dramatic catecholamine concentration changes in response to stressors suggests that these compounds could potentially be indicators of sublethal stress.

On an annual basis, from early 1900 through the mid 1950s, a 5-year moving average shows that overall basin temperatures increased. A cooler regime prevailed for the remainder of the period of record. Seasonal 5-year moving averages show that spring temperatures increased throughout the period. Summer temperatures were highly variable, but with an early upward trend through the mid 1940s and a recent downward trend for the remainder of the period. Fall temperatures slowly warmed from the early 1900s until the mid 1960s, but have recently shown a cooling trend. Winter temperatures show an upward trend with intermittent wide swings from the early 1900s through the mid 1950s after which a lower temperature regime has prevailed. Temperature differences between a warm and a cool year and the long term mean show markedly varying patterns.

The river's hydraulic characteristics naturally regulate Lakes Michigan-Huron's water levels by controlling the amount of water that flows out of the lakes. Accurate determinations of the outflows are necessary, in conjunction with the St. Marys River flows and lake level data, to determine the water supplies to Lakes Michigan-Huron. The hydraulic regime of the river has been changed many times since the mid-1800s primarily due to dredging for deeper draft navigation and sand and gravel mining. In addition there have also been minor effects due to shipwrecks at the head of the river. For water resource studies of the Great Lakes system it would be highly desirable to determine Lakes Michigan-Huron's water supplies for the period 1860-1900. Additional water supply values would extend the available period of study by 40 years or approximately 4.5 percent. This period is also particularly important as it contains extreme high water supplies that led to record Lakes Michigan- Huron water levels. This study comprised an analysis of the existing discharge and dredging data for the 1860-1902 period to determine if discharge equations could be developed with sufficient accuracy to compute monthly St. Clair River flows. The analysis demonstrated that it is not possible to quantify St. Clair River flows prior to 1900, thus limiting the period available for determining Lakes Michigan-Huron water supplies to this century. The study also confirmed the previously determined 0.18 m lowering of Lakes Michigan-Huron between 1900 and present due to channel dredging in the upper river.

These data were combined with the current measurements of Miller and Saylor (1993) to determine the sediment transport into and out of southern Green Bay. The data show that the sediment flux past Chambers Island is driven primarily by the non-tidal circulation in the two channels; both tidal and storm effects are of secondary importance. The cumulative sediment flux is southward through the western channel and northward in the eastern channel with a small net transport of sediment into the southern bay. Since the sediment load from tributaries to the bay is much greater than the transport in the channels, this excess sediment must be stored in the southern bay.

Daily transport estimates calculated from the current, temperature, and wind data, show temporal and spatial variability. Net summer transport during stratification west of Chambers Island was out of the lower bay (350 m super(3)s super(-1)) in the epilimnion, into the lower bay (900 m super(3)s super(-1)) in the hypolimnion, and out of the lower bay (320 m super(3)s super(-1)) through the passage east of the island. The residence time for the lower bay is reduced to less than 1 year using the above transport compared to a water balance estimate of over 3 years. During the mid-September to May isothermal period, a horizontal transport gradient existed. Under the solid ice cover of winter, transport variability was significantly reduced and was uniformly out of the lower bay (500 m super(3)s super(-1)). Fluctuations in daily transport were often large (up to 2 x 10 super(4) m super(3)s super(-1)). The temporal and spatial variability of the water volume transport suggests that material mass fluxes between lower and upper Green Bay will be similarly dependent.

The sites were characterized by relatively high and low mussel densities. The following variables were measured: ash-free dry weight (AFDW) per unit shell length (SL), lipid content and classes, carbon content, and nitrogen content. Mussels from the high-density site had a lower AFDW:SL relationship, lower lipid content, and a lower C:N ratio than mussels from the low-density site. Seasonal trends in these variables were consistent between sites and years. AFDW:SL, lipid, and carbon content were highest in the spring and then declined to minimum levels in late summer/fall. The mean seasonal decline in weight from spring to late summer for a standard 15-mm mussel was 60%. This decline was greater than might be expected from gamete release alone and was likely a result of nutritional stress from warm summer temperatures and limited food supplies. Between 1990 and 1991, the mean AFDW of a 15-mm mussel declined 34% and 50% at the high- and low-density site, respectively. However, when C:N ratios and lipid levels in 1990 and 1991 were compared, C:N ratios were only lower in fall 1991 compared to fall 1990, and lipid levels for the 2 years were generally similar.

These procedures may lower the transaction costs of assessments, encourage joint cooperative assessments, simplify most assessments and provide technical guidance for conducting assessments. DART is developing regulations for the assessment of damages due to injuries related to oil spills under the Oil Pollution Act of 1990. These regulations will involve coordination, restoration and economic valuation. NOAA encourages federal, state, tribal and foreign trustees, to develop prespill plans. Coordination with response agencies assures protection of important natural resources. The regulations provide an open record, which becomes the basis for judicial review. Various methods being developed to assess damages for injuries to natural resources include: compensation formulas for spills under 50,000 gallons of oil, the Type A model, expedited damage assessment (EDA) procedures, and comprehensive damage assessment (CDA) procedures which can be used for spills of various sizes. These procedures provide trustees with a choice for assessing natural resource damages to each oil spill. NOAA is emphasizing the importance of restoration. Restoration plans will define project goals and objectives, establish procedures and methods for site restoration, and define the approach based on sound science. Finally, numerous economic methods are identified to calculate the lost or diminished use and passive use of the affected resources.

This concern, be it real or perceived, stems from the fact that chemical contamination can exert a dual impact on living marine resources by directly affecting their health, reproductive potential and survival, and by contaminating seafoods that humans consume. To properly assess the significance and magnitude of this dual impact, we need to establish cause and effect linkages between contaminant exposure and deleterious effects. This need is urgent because our ability to detect minute levels of chemicals is rapidly advancing, but our understanding of the possible biological consequences is lagging far behind. Hence, we need to determine (a) which of the adverse biological effects in urban waterways are caused by contaminants; (b) which groups of contaminants are consistently identified as risk factors; (c) the levels and mechanisms by which contaminants exert toxic effects and (d) whether these effects observed in individuals can translate into population changes. Using a multidisciplinary approach combining field and laboratory investigations with a variety of marine organisms, we are attempting to develop such a database to help in ecological risk assessments. This database combined with our research on food chain contamination may also provide valuable information for human health risk assessments.

Only about 150 (four percent) of these events were suspected of being caused by pesticides. The data collected includes information on the location, extent, severity, timing, and cause of kill. Information was also collected on selected characteristics of each State's reporting program(s) to better understand the Nation's infrastructure for fish-kill reporting. Information on program organization, investigation procedures, on-site and off-site testing of fish tissue and water samples, documentation, distribution of fish-kill-related information, etc., was gathered. Data compilation was difficult because reporting responsibilities within most states are often shared by several agencies. Consequently, data are in varied formats and gaps occur in some states as a result of lapses in State programs or data lost during the transfer of program responsibilities. In addition, the level of activity, priorities, investigative procedures, documentation requirements, and reporting formats vary widely among states. As a result, the data content of the information characterizing fish kills varies from state to state. This lack of consistency in data content makes it difficult to make state-to-state and regional comparisons. However, if used properly, the data can provide natural resource planners and managers valuable insights into the location of possible problem areas.

D. polymorphs contributes to increased water clarity through extensive particle filtration. Because these particles contain sorbed contaminants, the potential for zebra mussel accumulation from both suspended sediment and algae was examined. Sediment or algae were dosed with radiolabeled polycyclic aromatic hydrocarbons and/or hexachlorobiphenyl (HCBP). Mussels were exposed to suspended dosed particles for 3 hours. Assimilation efficiencies depended on food quality. Zebra mussels, 17 ~c2 mm long, accumulated 26.6 ~c11.3 % of the pyrene and 44.7 ~c5.8 % of the Benzo(a)pyrene, (BaP) from sediment particles with a particle clearance rate of 493 -897 ml/g tissue/h, while the accumulation efficiencies were 91.7 ~c3.7 % for pyrene, 91.9 ~c1.4 % for BaP, 96.6 ~c1.4 % for chrysene and 97.7 ~c0.5 % for HCBP from suspended algae with a particle clearance rate of 47 -143 ml/g tissue/h. Thus, zebra mussels efficiently accumulated non polar contaminates sorbed to algae while only a small fraction of the sediment-associated contaminant was bioavailable. Further, the contaminates sorbed onto suspended sediment were quickly removed from the water and deposited as feces and pseudofeces.

However the incidence of toxicity was considerably higher in surveys performed with relatively sensitive taxa such as amphipods, as compared to pre-dredging studies performed with polychaetes shrimp, and clams. Areas that were most toxic included the upper East River, Arthur Kill. Sandy Hook Bay. Gowanus Canal, Newark Bay, and the lower Passaic River. Areas that were least toxic included the lower Hudson River adjacent to Manhattan Island upper New York Harbor and parts of the lower New York Harbor off Staten Island. Toxicity results were highly correlated with the concentrations of a number of toxicants. JF - 14th Annual Meeting (SETAC) - Ecological Risk Assessment: Lessons Learned? -- Abstract Book.

Our approach combines observations on contaminant exposure and response in feral, native organisms with sediment toxicity surveys that demonstrate the spatial distribution of sediment-associated contaminant effects. Sediment toxicity is estimated with multiple tests (using different test organisms, exposure media, and exposure durations), to ensure a robust assessment of potential effects, and to permit intercomparison of test sensitivities. In Tampa Bay, sediment toxicity tests (Ampelisca survival with whole sediment, sea urchin egg fertilization success with porewater, Microtox super(TM). with organic extracts and growth of juvenile polychaetes Armandia and sand-dollars Dendraster), consistently indicated that the northern portions of Hillsborough Bay were most toxic. Nearshore sediments from other parts of the Bay also exhibited toxicity with one or more tests. The sea urchin test was the most sensitive of the tests used. The pattern of sediment toxicity was consistent with the distributions of concentrations of many contaminants in sediments, and in native fish and shellfish from the Bay. Native oysters from locations in northern Hillsborough Bay also exhibited signs of stress, including reduced condition indices, reduced protein content, and more histological anomalies, relative to those from other sites.

For protection of natural resources, the primary vehicle for the assessment of risk, and the basis for risk management decisions, is the Ecological Risk Assessment. The most common approach to Ecological Risk Assessments currently being employed is an adaptation of the indirect risk assessment method commonly used for human health assessments- the Hazard Quotient ratio. This approach assesses risk by comparing exposure levels to some toxicological benchmark value. However, it evaluates risk on an individual chemical basis in chemical-specific ratios. The cumulative, joint action from all of the compounds an organism may be concurrently exposed to is often not evaluated. On occasion, it is assumed that toxicity is additive, and Hazard Quotients are summed to a Hazard Index. This paper will present a review and summary of current literature on joint action, or toxicity of chemical mixtures, with an emphasis on aquatic resources. Results from toxicity tests of binary or complex mixtures are synthesized to provide overall guidelines on chemical interactions. The intent of this review is to provide for risk management decisions based on sound scientific inferences regarding the cumulative risk of joint action, rather than on mere assumptions. A general framework for the interpretation of chemical interaction will also be presented. JF - 14th Annual Meeting (SETAC) - Ecological Risk Assessment: Lessons Learned? -- Abstract Book.

Although both species showed high correlations between tissue and sediment concentrations, the bioaccumulation factor (BAF) was higher in the worm for most PAHs which was probably due to sediment ingestion. Analysis of the ratio of PAH BAFs for the two species indicated that they had equal BAFs for the LPAHs but the worm was able to accumulate much more HPAHs than the amphipod. Results of a study with radiolabeled benzo(a)pyrene, a HPAH, indicated that differences in metabolism of PAHs could not account for the observed species differences in bioaccumulation. However, the relationship between body burden and interstitial water concentration did help explain the patterns of accumulation. We conclude from this study that water may be the dominant route of exposure for LPAHs, but that ingestion may be more important for body burden accumulation for HPAHs, particularly for the worm. This study demonstrates that bioaccumulation of contaminants in invertebrates at sublethal concentrations is an important way to assess contamination in sediment and that these important prey items for fish are potential vectors of toxic chemicals from the sediment into higher trophic levels.

DuPont, Newport Superfund site is a pigment manufacturing facility with two associated industrial landfills separated by the Christina River. Wetlands adjacent to the landfills have become contaminated with metals from the waste, as have the sediments of the Christina River. As part of the ecological risk assessment for the site, benthic community studies and toxicity tests were performed. Sediments from the wetlands and river showed toxicity to amphipods, chironomids, daphnids, and fathead minnows in laboratory tests. A weight of evidence approach was used to indicate that ecological risk is significant enough to justify remediation. Site-specific sediment cleanup criteria were developed for five metals. Several strategies used to develop sediment cleanup criteria using the results of toxicity testing are discussed in this paper. First, a range of concentrations was established for each metal that indicated the maximum concentration where sediments were and were not toxic. The maximum concentration associated with no toxicity was one possible cleanup level. Second, correlations between individual contaminant concentrations and toxicity to Hyalella azteca were attempted. Third, a toxic unit approach was developed using summed ratios of sediment concentrations to ER-M values. These toxic units were then correlated to Hyalella azteca toxicity. Sediment toxicity was apparently caused by different contaminants at different stations. This paper illustrates the complexities involved where multiple contaminants are present that may be contributing to sediment toxicity.

Under this authority, the National Oceanic and Atmospheric Administration represents the public as a Federal Trustee for coastal resources and habitats. As part of its trustee responsibilities, NOAA assesses and claims damages (compensation) for injuries to natural resources from discharges of oil or releases of hazardous substances. Recovered damages are used to restore, replace, or acquire the equivalent of the injured resources. To implement its resource restoration and trustee responsibilities in a timely and cost-effective manner, NOAA created the Damage Assessment and Restoration Program (DARP). The Restoration Center (RC) was established within the National Marine Fisheries Service to use recovered damages to restore the injured resources and to address research and development priorities necessary for successful resource habitat restoration. The Center also is responsible for basic and applied research to advance understanding of habitat functioning and habitat response to natural and human-induced environmental changes, to develop improved techniques for habitat restoration and assessment, and to support the habitat permit-review process within the agency. This paper will describe common practices that the RC interacts with other NOAA organizations and approaches used in evaluating restoration alternatives for specific DARP cases.

N.A. This facility has affected the nearshore marine ecosystem through both oil contamination at the harbor and tanker berths, and from disturbance related to shipping, dredging and Construction. The impact of this facility on nearby coral reef communities was studied from January 1987 to August 1989. This included an analysis of reef community structure comparing sites adjacent to the refinery with those upstream and downstream, the modem and historical growth of the predominant coral species, and recruitment of new corals. Both upstream and downstream control sites were in good health and exhibited high diversity .In contrast, reefs adjacent to the refinery exhibited low density and diversity of live corals and abundant dead coral rubble. Additionally, periods of construction in the inner harbor and on surrounding spoil islands and high refinery activity corresponded well with periods of reduced coral growth near the refinery. Although the relative importance of oil contamination, sedimentation and other anthropogenic effects is uncertain. our observations suggest that sedimentation and other physical stress resulted in substantial reductions in environmental quality at the disturbed sites. Coral recruitment at the highly impacted sites showed hope for recovery if these environments are protected from renewed perturbation. JF - Global aspects of coral reefs: Health, hazards and history.

CYP1A was determined by two catalytic assays [aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin-O-deethylase (EROD) activities] and by an ELISA utilizing polyclonal antibodies to purified cod CYP1A. Juvenile fish were used to minimize effects of reproductive status and migration associated with spawning. For each species, whenever at least four composite samples from each site were analyzed, all three CYP1A measures showed significant between-site differences over the course of one year, indicating that CYP1A is a reliable biomarker of contaminant exposure in fish if certain biological variables are controlled for in-field studies. Immunologic assay, while less sensitive than either catalytic assay, is nonetheless recommended for use in conjunction with catalytic assay in monitoring programs to provide additional quality assurance in CYP1A measurement. Both catalytic activities are suitable for assessing CYP1A induction, but AHH activity appears to be less variable, making it potentially more useful for assessing temporal trends in monitoring programs.

In situ toxicity tests were conducted using a variety of crustacean (Palaemonetes pugio, Penaeus species (aztecus and setiferus), and Mysidopsis bahia) and fish (Cyprinodon variegatus, Fundulus heteroclitus, and Menidia betylina) species at two agricultural sites (TAT and KWA) and one reference (CTl) site from 1985-91. During this time period significant runoff of insecticides at the TAT and KWA Sites, resulted in several fish kills and significant mortality in fish and crustaceans caged during each in situ toxicity test. Comparisons of mortality rates among the different crustacean and fish species from field exposures were then compared to laboratory predicted toxicity tests for each of the three pesticides studied. Additional comparisons of field biomonitoring data for Palaemonetes pugio and Penaeus sp. were made. Results suggested that comparative species toxicity estimates from laboratory toxicity tests provided accurate ecotoxicology estimates of field mortality for most of the estuarine fish and crustacean species evaluated.

Thus levels of TBT, as well as biotransformation products, dibutyltin (DBT) and monobutyltin (MBT) were measured in sediments and livers of fish collected at 37 urban and nonurban embayments on the East, Gulf and Pacific Coast of the U.S. Livers of 10 fish species were analyzed and similar to 50% of all samples contained detectable concentrations of butyltins. Tributyltin represented 80 plus or minus 33% (mean plus or minus sd; n = 9), 60 plus or minus 21%. In = 11) and 49 plus or minus 30% (n = 9) of the total butyltins in livers from white croaker, winter flounder a~ Atlantic croak, respectively. Generally, the highest butyltin concentrations in both sediments and tissues were found at sites on the Pacific coast. Butyltin concentrations were also determined in liver, kidney and muscle of English sole and starry flounder exposed to a single dose of TBT in the laboratory. Preliminary results showed differences in the TBT /DBT ratio in livers of these two species for several weeks after exposure to TBT. These data suggest possible species differences in the metabolism and disposition of TBT in fish. JF - 14th Annual Meeting (SETAC) - Ecological Risk Assessment: Lessons Learned? -- Abstract Book.

Long and Morgan (1990) calculated concentrations that have been used in absence of other values as guidelines for the evaluation of sediment contaminant concentrations having the potential to effect biological resources. Using data from the NOAA National Status and Trends (NS and T) Program and the U.S. EPA's Environmental Monitoring and Assessment Program (EMAP), we applied the Long and Morgan approach to a 500+ record database containing results from the 1O-day acute Ampelisca abdita sediment toxicity test and bulk sediment contaminant concentrations. The 10th and 50th percentile concentrations for sites showing positive toxicity results (approximately 100 records) were calculated for trace elements, PCBs, chlorinated pesticides, and PAH compounds. Values were generally 10 times lower than the corresponding ER-L and ER-M values of Long and Morgan. Of greater note, was the finding that there was a greater number of sites with negative toxicity results compared to sites with positive toxicity results above the calculated ER-M concentrations. Therefore, we urge caution in using bulk concentrations to categorize sediment contaminants in terms of biological significance.

The Hg contamination has resulted in a portion of the Bay being closed to commercial and recreational fishing due methylmercury (meHg) concentrations in excess on 1 ppm (FDA Action Limit). This investigation has concentrated on describing the food web relationships that result in elevated concentrations of meHg in blue crabs, Callinectes sapidus. Descriptive models of the food web relationships for the blue crab and the food webs supporting the crabs have been constructed. This discussion will concentrate on feeding strategies, food web dynamics, and sources of variability that affect the accumulation of meHg. Since the data on meHg concentrations in organisms from Lavaca Bay was limited, a majority of the information used in the implementation of the blue crab model was drawn from the literature. Our calculations of meHg accumulation utilizes a steady state models for different size classes of crabs. When the effect of growth on accumulation is included, the estimates of meHg concentrations in blue crabs fall within the range of concentrations measured by the Texas Department of Health in the closed portion of Lavaca Bay.

The project objectives are to define a methodology of incorporating long range probabilistic forecasts into reservoir operations and quantify the benefits of the forecast information. The Denver Water Department (Colorado) has the primary responsibility to provide adequate water to subscribers in the Denver Metropolitan area. In doing so it diverts water from the Colorado River Basin to Eastern Colorado, sells hydroelectric power, while complying with other competing water rights and commitments in the water supply network. The Extended Streamflow Prediction System (ESP) developed by NOAA/NWS was used to supply probabilities of equaling or exceeding weekly, monthly, or seasonal flows. Strategies based upon these probabilities and modeling techniques developed at Colorado State University were applied to the water supply system. Initial results show how a reliable water supply was assured and overall usable water yields from the reservoir system were increased while optimizing benefits from other competing demands, such as, hydropower and recreation.

B-cell immune function was assessed by examining the in vitro anterior kidney and splenic leukocyte primary and secondary plaque-forming cell (PFC) responses to a T-independent antigen, trinitrophenyl-lipopolysaccharide (TNP-LPS) and to a T-dependent antigen, TNP-keyhole limpet hemocyanin (TNP-KLH). Salmon exposed to sublethal concentrations of these contaminants have a suppressed PFC response. The secondary PFC response of anterior kidney and splenic leukocytes of salmon exposed to either DMBA or Aroclor 1254 was suppressed to both forms of antigen. Juvenile chinook salmon exposed to either DMBA or Aroclor 1254 also had a suppressed primary splenic PFC response to TNP-LPS. However, only anterior kidney leukocytes from salmon exposed to Aroclor 1254 had a suppressed primary PFC response to TNP-LPS. Neither anterior kidney nor splenic leukocytes from salmon exposed to DMBA or Aroclor 1254 had an altered primary PFC response to TNP-KLH. These results suggest that the PFC assay is a sensitive bioindicator of immune dysfunction to both PAH or PCB exposure in juvenile Chinook salmon.

The model predicts mercury accumulation by the benthic prey of the fish using constant biota sediment factors (BSF). Model predictions of mercury accumulation by fish from their prey depend, in turn, on a simplified bioenergetic equation, incorporating parameter estimates of weight specific rates of feeding, growth, and methylmercury excretion. This is coupled to species specific patterns of feeding on prey of different methylmercury concentrations. When model predictions of mercury concentrations in the two target species are compared to past site specific monitoring data (Texas Dept. of Health), surprising similarity is observed, despite the use of model parameter estimates selected mostly from generic literature values. The simplicity of the model and its predictive success is attributed to the simplicity of the food web supporting the two fish species, the directness of its linkage to contaminated sediments, and the non-migratory behavior of the fish.

It is found that the step motion with respect to a stagnant solution provides stabilization at sufficiently large wavelengths for which the typical diffusion rate is comparable to the rate of incorporation of the crystallizing species at the steps, i.e. to the kinetic coefficient. Since capillarity can stabilize the interface against short wavelength perturbations, the combined action of both kinetic anisotropy and capillarity provides complete linear stability at sufficiently high growth rates.

There are several vital areas that have not received adequate attention. Particular improvements are needed in the interaction between network designers and climatologists; operational analyses that focus on detecting and documenting outliers and time-dependent biases within datasets; developing the means to cope with and minimize potential inhomogeneities in weather observing systems; and authoritative documentation of how various aspects of climate have or have not changed. In this last area, close attention must be given to the time and space resolution of the data. In many instances the time and space resolution requirements for understanding why the climate changed are not synonymous with understanding how it has changed or varied. This is particularly true within the surface boundary layer. A standard global daily/monthly climate message should also be introduced to supplement current Global Telecommunication System's CLIMAT data. Overall, a call is made for improvements in routine weather observing, data management, and analysis systems.

To compare the functional development of the digestive system in altricial and precocious larvae, we developed a method for force-feeding radio-labeled nutrients to fish larvae. The method involves micro-injection of diets into the gut of anesthetized and immobilized larvae in a petri dish under a dissecting microscope. Three protocols are described illustrating the application of this method to studies of larval digestive function. To determine the development of acid digestion, pH indicator solution was injected and the gut of the transparent larvae was monitored for color change. To determine nutrient assimilation efficiency, radio-labeled nutrients were injected. After a period of time, counts of the recovery water and the larvae were made using liquid scintillation counting. Finally, to determine sites of nutrient uptake, radio-labeled nutrients were force fed to larvae that were subsequently examined by microscopic autoradiography. The utility of this method is illustrated with observations of protein, polypeptide and free amino acid assimilation in larval walleye (Stizostedion vitreum) and pH changes in larval striped bass (Morone saxatilis).

In particular, we examine the specific differential phase, the backscatter differential phase, the correlation coefficient between vertically and horizontally polarized waves, and the differential reflectivity, collected from a storm at close range. Three range-height cross sections are analyzed together with complementary data from a prototype WSR-88D radar. The case is interesting because it demonstrates the complementary nature of these polarimetric measurands. Self-consistency among them allows qualitative and some quantitative discrimination between hydrometeors.

Selectivity is based upon lithium chloride, colistin methane sulfonate, and ceftazidime. When horse blood was incorporated in the agar overlay, L. monocytogenes colonies were easily distinguished by their characteristic blue-gray color surrounded by narrow zones of beta -hemolysis. Listeria innocua, a species commonly present in foods, does not produce hemolysis on the medium. Therefore, one or more colonies of L. monocytogenes were easily distinguished from large populations of L. innocua. When used in combination with Food and Drug Administration and U.S. Department of Agriculture enrichment methodology, HCLA was effective in inhibiting competitive organisms, differentiating colonies of L. monocytogenes by their beta -hemolysis, and shortening the incubation time at 35 degree C for presumptive identification to 17-24 h.

The primary sources of data were radar microfilm and manually digitized radar (MDR) reports from the operational National Weather Service (NWS) radars at Cape Hatteras (HAT) and Wilmington (ILM), North Carolina. The dataset also included cloud-to-ground lightning flashes that were recorded by the network operated by the State University of New York at Albany. The analyses included rainbands of at least 90-km length with lifetimes of at least 2 h. Nearly all of the rainbands were within 400 km of synoptic-scale or coastal fronts. Warm-sector rainbands predominated. Rainbands were classified by the location of their initial detection relative to the land, coastal shelf, and Gulf Stream. Rainbands were initially identified more frequently over the Gulf Stream and less often over the coastal shelf than the corresponding fractional areas monitored by the radars. Statistical tests determined significant differences in the sample means of the MDR and lightning data between the Gulf Stream and land regions that were largely a consequence of many more hours with MDR and lightning over the Gulf Stream. Composites relative to the beginning and ending of the rainband cases indicated that differences between the Gulf Stream and land were small shortly after the initial detection of rainbands and large just before the final detection of rainbands. The largest Gulf Stream-land disparities occurred, on the average, during low-level cold and dry advection at HAT. Trunk and Bosart reported a convective echo maximum over the Gulf Stream near HAT and discussed physical processes that can account for the convective maximum. Analysis of one idealized distribution of convection, however, supports the likely role of sampling limitations of the NWS radar network in determining the location of the convective echo maximum near HAT.

These drops, which give a distinct radar signature termed the "differential reflectivity column," originate from 1) melted hydrometeors that fall from the back-sheared anvil, through the embryo curtain, and are recirculated into the storm updraft, and 2) in situ drop growth within the updraft. Some of the drops refreeze and likely produce frozen-drop hailstone embryos. Numerous hailstone trajectories are found to cross either through, or over, the drop column where the hailstones undergo a significant growth phase. Two separate hailstone fallout regions are identified. Some hailstones in the northern fallout region show anticyclonic trajectories and in situ updraft and column growth. Others grow while crossing the top of the vault. Hailstones in the southern region exhibit growth while passing cyclonically through the column or over the vault. A new method to determine hydrometeor fall speeds from radar polarization measurements for use with dual-Doppler analysis is introduced.

We use environmental response surfaces to calibrate modern pollen data (for 17 different taxa) to an index of effective soil moisture and mean annual precipitation. We apply these response surfaces to fossil pollen data from 60 sites in the region to reconstruct changes in soil moisture and mean annual precipitation at 3000-yr intervals from 12,000 yr B.P. to present. The mapped reconstructions of soil moisture and mean annual precipitation illustrate how the regional moisture balance of the Northeast may have changed over the last 12,000 yr in response to changing climate. Reconstructions of annual precipitation show a gradual increase from 30% below modern values at 12,000 yr B.P. to near-modern values by 6000 yr B.P. and then remain relatively constant thereafter. Reconstructed changes in the index of effective soil moisture, however, show a pattern of near-modern values at 12,000, 6000, and 3000 yr B.P., with significantly lower values estimated for 9000 yr B.P., the time of maximum pine pollen abundances in the Northeast. This pattern of change is similar to the change in regional moisture balance inferred from stratigraphic records of water-level fluctuations. These results confirm previous interpretations, based on records of water-level fluctuations, that conditions in the Northeast were significantly drier during the early to middle Holocene than at other times during the last 12,000 yr.

A deep layer of warm, moist, southwesterly flow overran a shallower layer of subfreezing, easterly flow ahead of a surface warm front. Precipitation at the surface changed from snowfall to ice pellets, to freezing rain, and, finally, to ordinary rain as an elevated layer of above-freezing air moved into the region and eventually extended to the ground. Measurements from a scanning Doppler radar, wind profilers, a microwave radiometer, and mobile rawinsondes provided detailed information on the storm's kinematic and thermodynamic structure and evolution, and allowed its basic microphysical structure to be inferred. The remote sensors detected signatures of the melting aloft that may be useful for improving detection and forecasts of freezing-rain hazards.

These areas are usually located in shallow, energy rich coastal areas where the young find abundant food and have little predation by larger sharks. Nurseries are characterized by the presence of both gravid females and free swimming neonates. Neonates are young bearing fresh, unhealed umbilical scars in the case of placental species, or those at or near the birth size in aplacental species. Bulls Bay, South Carolina, is a nursery for the blacknose, spinner, finetooth, blacktip, sandbar, dusky, Atlantic sharpnose, scalloped hammerhead, and smooth dogfish sharks. The lemon shark has its nursery in shallow waters of south Florida and the Bahamas. The bull shark has its nursery in the lagoons of the east coast of central Florida.

Length and sex were recorded for an additional 188 males and 272 females. Ages were determined by counting dentinal growth layer groups. Female reproductive status was determined by macroscopic examination of ovaries; 67 were mature. Sixteen percent were pregnant, 3% were pregnant and lactating, 33% were post partum, 24% were lactating (no recent pregnancy), 10% were resting, and 14% were of unknown condition. Testis and epididymis were examined for evidence of spermatogenesis; 28 were mature. Three estimates of length at birth were 99.7, 100.6, and 103.8 cm. The gestation period was 12.1-12.3 months. The sex ratio at birth was not significantly different from 1.0; the male component decreased with age. Estimates of the average age at sexual maturation among males were 9.9 and 10.1 years; average length at sexual maturation was estimated at 215.1 and 214.7 cm. Mature testis masses ranged from 117.4 to 1300 g. Estimates of the average age at sexual maturation among females were 9.7 and 10.4 years; the average length at sexual maturation was estimated at 201.1 and 199.8 cm. Males reach an asymptotic length of 265 cm, females 210 cm. Ovulation rates were <1.0/year. Calving appeared to peak in July and August; the minimum calving interval was 2 years.

Three- to 5-month-old fish were afflicted with a variety of parasites and pathologic conditions. A few conditions, including gastritis, inflammatory heart conditions, and the only occurrence of gill bifurcation, appeared only at Gaspee Point, the most contaminated site sampled in the bay. The microsporidan Glugea was found in only one fish from the least contaminated site. Some conditions appeared more frequently in the older fish than in the younger ones; trematode metacercaria (Cryptocotyle) infections increased at two stations from 20% in June to 100% in August, while infection intensities increased from 1 to 2 cysts of metacercaria per fish in June to 188 cysts per fish in August (it is notable that metacercariae were not found on fish from the most polluted site); epitheliocystis-like lesions in gills increased from 2% in June to 59% in August; gill hyperplasia and fusion increased from 24% in June to 41% in August. This study reports on melanized fibrosis in the liver and parasites (coccidians and myxosporidans) not previously recorded in winter flounder. These conditions are discussed relative to year-class success. JF - American Fisheries Society Symposium [AM. FISH. SOC. SYMP.]. 1993.

Despite this lengthy relationship, little is presently understood about the precise developmental events that result in the formation of these morphological aberrations. This brief review is restricted to terata that result from exposure of embryos to contaminants. Recent reviews of this subject render any attempt to cover all the pertinent literature redundant; therefore, only general information is considered for work published prior to 1988. The teratogenic response of fish embryos to toxicants is non-specific. However, when carefully studied by quantitative methods in environments stressed by pollution and overfishing, a knowledge of the prevalence of embryos bearing these abnormalities may be useful in studies of recruitment. In addition to terata, pathological lesions in embryos and newly hatched larvae, resulting from contaminant exposure during embryogeny, are also reviewed.

The indices, estimated simultaneously for individual fish, rely on measurements of RNA and DNA content by flow cytometry of single cells dissociated from the walleye pollock brain. Nutritional condition was estimated from the fraction of brain cells that exhibited distinct RNA activity among larvae that were always fed, always starved, and starved before feeding. Fast- and slow-growing larvae were discerned by differences in their DNA synthetic activity, the potential for replication. We describe a simple method for freezing the dissociated brain cells that ensures nucleic acid stability during storage, thus permitting sampling and storage at sea. We envision that in the field, with a flow cytometer onboard the research vessel, a quick and accurate assessment of individual fish condition could be obtained on site.

During their development, estuarine dependent fishes utilize a wide variety of habitats in the coastal environment as well as within the estuary. Early life-history research has emphasized life-history patterns, abundance, and distribution of fishes in coastal waters and not the habitat they utilize per se. Limited data suggest that there are differences in coastal habitat quality that may cause differences in the growth of larvae. Within the estuary, habitats usually have been described by their physical structure, but there is a paucity of data on the actual use of these habitats by larvae and early stage juveniles. We discuss some of the available information for several habitats common to the east and Gulf coasts of the U. S. and conclude that within estuaries the water column and seagrass meadows provide the primary habitats for initial use, but that other habitats are integrally linked through biological, chemical, and physical processes. Because of the coupling between habitats, we recommend that research be addressed more on a basis of landscape, rather than individual habitats. JF - American Fisheries Society Symposium [AM. FISH.

The analysis compared the change in potential lifetime fecundity of an age-1 female due to changes in fishing mortality rates versus changes in age-0 survival, presumably due to alteration of the habitat for age-0 life stages. The relative change in the baseline rate of age-0 survival, both positive (due to habitat restoration) and negative (due to habitat loss), was found to approximate the relative change in fishing mortality rate necessary for an age-1 female to attain a specified level of potential egg production during her lifetime. Regulating fisheries to increase stock abundance and yield may represent less risk to managers than undertaking habitat restoration programs, in terms of predicting the outcome. However, undertaking habitat restoration programs should not be dismissed outright, since they may result in longer term benefits to reproductive success and provide managers with a firmer basis to increase fishery yield in the future.

The report will assist National Marine Fisheries Service efforts to assess the impacts of the driftnet fisheries on threatened and endangered sea turtle populations. The species of concern are the green sea turtle complex (Chelonia mydas), loggerhead sea turtle (Caretta caretta), olive ridley sea turtle (Lepidochelys olivacea), hawksbill sea turtle (Eretmochelys imbricata), and leatherback sea turtle (Dermochelys coriacea). The populations of interest include those whose members may be encountered in the epipelagic waters of the North Pacific. The document presents information on a broad range of topics germane to sea turtle taxonomy, life history, distribution, and exploitation. Relevant national and international conservation legislation is also summarized.

As a result, competition between fisheries on the fishing grounds and in the marketplace has also increased. Physical conflicts between vessels and claims of decreased fishing success by surface (troll and handline) fishermen led to the enactment of federal regulations limiting the number of domestic longline vessels and the areas in which they can operate. The scientific evidence of biological or economic fishery interaction between longline and small-vessel fishermen is limited but suggests that intense longline fishing near the Hawaiian Islands has the potential to affect catch rates in other Hawaii fisheries. Better data collection and more research are needed to document fishery interaction and to improve fishery management.

Females generally exhibited site fidelity in their choice of birth sites, and arrived a mean of 1.8 days prior to birth. After birth, females stayed ashore a mean of 9.8 days before departing on their first foraging trip. Trips to sea were about 48 h in length although there was significant variation over time. Stays ashore were about 33 h long and were much less varied than trips to sea. Females moved pups away from the natal areas after about 1 month, and began spending less time with them while they were ashore. Linked with the extended breeding cycle of 17.6 months was an equally long period of maternal investment. Females suckled their pups for 15-18 months, or until about 1 month before the next birth. Twenty-nine percent of females did not pup consecutively each breeding season, but continued to suckle their offspring until the next birth, some for as long as 40 months.

Total Hg and Se both occurred in very high concentrations in liver and kidney and in liver were significantly correlated with animal length (and each other) which indicates bioaccumulation over time. Methyl mercury, as a percentage of total Hg, varied inversely with total Hg indicating demethylation was occurring; a one-to-one molar association of Hg and Se was found which is believed to provide protection against Hg toxicity. Arsenic concentrations were relatively low, but Cd concentrations were consistently very high in adult kidney. Lead in adult liver was also correlated with animal length indicating long term bioaccumulation. All non-essential elements were found in critical fetal tissues which indicates maternal transfer occurred. Cadmium in fetal kidney was over 30 times higher than either brain or liver, indicating early differential accumulation and supporting maternal transfer. Matched pairs of mother and fetus liver indicated no correlation of elements, which may due to the temporal nature of bioaccumulation and the immobility of some elements. The results were compared to other mammalian studies to evaluate the toxicological implications of observed tissue concentrations.

The source of the data is a subset of the National Oceanographic Data Center. Nutrients in surface waters are enriched in upwelling and high latitude regions and are generally depleted at mid-latitudes. The depletion at mid-latitudes is associated with the subtropical anticyclonic gyre systems. With increasing depth, the nutrient content increases in the water column. At depths of more than 1000 m, the nutrient distributions are associated with different water masses which have their own inherent characteristics.

The multispecies spatial patterns that emerged imply the existence of persistent and geographically distinct larval fish assemblages off both coasts. Four assemblages were identified off the west coast. They include a coastal assemblage that was restricted to coastal and continental shelf waters mainly off Washington and Oregon; a slope/transitional assemblage that occurred largely along the shelf edge and slope; a Columbia River plume assemblage that was associated with the Columbia River plume during summer; and an oceanic assemblage that prevailed in deep water beyond the shelf edge and for which northern and southern components were apparent during winter and spring. The east coast assemblages include a Gulf of Maine and Georges Bank assemblage; an oceanic assemblage that was associated with the continental shelf edge and slope; and a Middle Atlantic Bight assemblage that occurred along the shelf from Cape Cod, Massachusetts, to Cape Hatteras, North Carolina. Northern, southern, inshore, and offshore components of the Middle Atlantic Bight assemblage were apparent at certain times of the year. In general, the boundaries to the assemblages are fluid, and seasonal variation in occurrence and abundance of species within assemblages is strong. The distribution of the larval fish assemblages reflects spatial structure in the oceanographic environment and, in some instances, can be related to specific hydrographic features. Among the fish taxa in both regions, adaptation of the spawning patterns to the prevailing oceanographic conditions is apparent. Co-evolution among the fishes' spawning strategies within the complex and variable marine ecosystems may have given rise to the high degree of structure observed in the ichthyoplankton spatial patterns and to the larval fish assemblages themselves. It is not possible to conclude from this limited study that the multispecies larval fish assemblages are independent ecological entities that enhance survival of the constituent species. Further investigations of finer scale spatial patterns within the larval fish assemblages and among different ontogenetic categories, as well as consideration of the zooplankton, of which fish larvae form only a small part, are necessary to understand fully the multispecies spatial patterns that prevail.

Organic solvent extracts of all 33 sediments showed some degree of toxicity, with sediment samples from sites in the urban areas of the bays being significantly more toxic than those from less urbanized areas of the bays. Saline extracts, however, were less toxic, only seven of 33 saline extracts produced a significant response using the recommended method of data analyses. The proportional decrease in bacterial light production at the highest concentration of saline sediment extract in the reaction mixture compared to the bacterial light production in the controls (saline light change--SLC) appeared to be a better indicator of sediment toxicity than generating a saline EC sub(50) (the amount of sediment required to reduce bioluminescence 50%) value; 16 of 33 saline extracts produced a significant response ( greater than or equal to 10% reduction in bioluminescence).

These activities employ a myriad of physical, chemical and biological technologies. Some, such as advanced wastewater treatment, have been with us for over a century. Others such as bioremediation are just coming into their own. As technology-based solutions are implemented, costs soar. And as costs soar, the public, policy-makers, managers and scientists are beginning to challenge the technology, demanding more information on what works and what doesn't, on efficiencies and efficacy and, indeed, on whether specific technologies are needed at all. Meanwhile, marine scientists, using survey technologies of the nineteenth century coupled with state-of-the-art analytical chemistry, are reporting that pollution is decreasing in many coastal areas (NOAA, 1992). This article is written to stimulate debate on a simple question. Are we using appropriate technologies to control marine pollution? and to offer some guidelines on what does constitute appropriate technology after the fact.

From 1988-92 salmon farms increased in number from 10 to 21, and raised over 12 million pounds of round weight fish worth some 37 million dollars. This economic benefit has provided newjobs in areas depressed because of a lack of income, resulting from previous dependence on wild fisheries (e.g. herring Clupea harengus ) which were over fished and depleted. While federal regulations are strict concerning adverse changes to coastal waters resulting from salmon waste, federal regulators have worked actively with states to streamline the permitting process, enabling permittees to satisfy the codes of one entity rather than a group of agencies, often with conflicting permitting requirements. In 1990, aquaculture production throughout the U.S. exceeded 860.8 million pounds with a value of $761 million dollars, a four-fold increase from 1980. Of these amounts, U.S. marine aquaculture accounts for 119.5 million pounds and 114.5 million dollars. JF - ICES, COPENHAGEN (DENMARK). 1993.

Here we will focus on a major component of NS&T, the Mussel Watch Project, and on the status and trends of chemical contamination in mussels and oysters. Since 1986 the Mussel Watch Project has been measuring chemical concentrations in whole soft-parts of mussels and oysters collected from coastal and estuarine sites. Where temporal trends exist, contamination is usually decreasing. This finding implies that some benefits have resulted from the imposition of controls on chemical use and discharge. However, data for more years will be necessary to distinguish the effects of human activity from those of natural influences on some of these chemical concentrations.

The river forecast system operates on scientific work stations using hydrometeorological models and software to predict inflows into the high Aswan Dam and forecast flow hydrographs at selected gaging locating above the dam. The Nile Forecasting System (NFS) utilizes satellite imagery from the METEOSAT satellite as the input to the forecast system. Satellite imagery is used to estimate precipitation over the Blue Nile Basin using five different techniques. Observed precipitation data and climatic statistics are used to improve precipitation estimation. Precipitation data for grid locations are input to a distributed water balance model, a hill slope routing model, and a channel routing model. A customized Geographic Information System (GIS) was developed to show political boundaries, rivers, terrain elevation, and gaging network. The GIS was used to develop hydrologic parameters for the basin and is used for multiple display features. JF - Water Resources Bulletin AU - Barrett, C B AD - NOAA, Natl.

M. Flower Company, Bluepoints Company, and Long Island Oyster Farms. There were nine industry attendees and six Milford staff. In subsequent years the forum broadened in technical scope, covering topics of algal rearing, genetics, and water quality control, and organized as a technical exchange from Government scientists to shellfish industry representatives. Since 1980, the scope of the seminar has further expanded to include presentations by aquaculture scientists from Sea Grant, academia, and other state and federal agencies, as well as the commercial aquaculture companies. The purpose of these annual gatherings of shellfish biologists was to share current ideas and innovative methodologies in shellfish research. This year the name was changed from "shellfish" to "aquaculture" seminar to focus attention on other marine species of commercial interest.

As yet, the cause of these mortalities has not been resolved, although many possible causes have been hypothesized. Our hypothesis is that this is an infectious disease process, with mortalities possibly resulting from pathology associated with a protistan parasite. Based on this, transmission experiments were designed to determine if the disease could be transmitted under controlled laboratory conditions. Preliminary results of ongoing experiments support this hypothesis. JF - Journal of Shellfish Research AU - Lewis, EJ Jr AU - Farley, CA AD - NOAA/NMFS, Northeast Fish. Sci.

The first permanent assignment of a full-time biologist and plans to establish a laboratory in Milford, Connecticut, occurred in 1931. The development of methods for commercial shellfish cultivation began in 1944. During that decade, federal biologists established procedures for conditioning eastern oysters to ripeness, inducing spawning and fertilization, rearing larvae, determining food requirements, and growing newly-set spat. Activities at this facility have continued on a variety of subjects including natural diets, genetics, disinfection techniques for hatchery water, and culture methods for eastern oysters, bay scallops, and Atlantic surfclams.

Our previous laboratory exposures of one Prorocentrum minimum isolate (strain EXUV) to hard clams and bay scallops demonstrated clear differences in responses of the two bivalves; hard clams survived but did not grow, whereas scallops experienced complete mortality in 1-4 weeks. Histological evidence suggested effects of an enterotoxin upon scallops.

Vibrio bacteria isolated from TCBS media as yellow and green colonies at different concentrations, as well as a seawater wash from diseased juvenile oysters, were used to challenge embryos. No normal larvae developed after 48 hours in cultures at highest concentrations of bacteria; some normal larvae developed at lower concentrations, however, these were smaller than control larvae. In these assays, vibrios from some colonies appeared more toxic than others. Although a greater percentage of embryos developed into normal larvae in the seawater wash than in the cultures challenged with bacteria, mortality was higher than in the cultures challenged with bacteria. Cytogenetic and cytological observations showed delayed and arrested development as evidenced by elevated frequencies of non-dividing cells in embryos. Results suggest that selective mortality occurs early in oysters after exposure to bacteria or wash water from diseased oysters.

Decisions on protective actions during emergencies are often based on dose calculations using the dispersion models. In view of the importance of such decisions, it is essential to understand and quantify the uncertainty associated with modelled concentrations. Two kinds of uncertainty, "reducible" and "inherent", are emphasised. The reducible uncertainty can be minimised through more accurate and more representative measurements and better model formulations. The inherent uncertainty arising from unmeasured or unresolvable details of the atmospheric flow leads to random fluctuations of concentrations from individual calculations about their ensemble average. When these fluctuations are large, the mean concentration alone is inadequate to predict the range and probability of the concentration levels. In this paper, the various uncertainties in the assessment of atmospheric concentrations are discussed and some aspects of model evaluation are illustrated with examples using gaussian puff/plume models and tracer data.

When tagged fish are released in an area small compared with the domain of the fish population and over a period short compared with the time they take to disperse throughout their domain, the pattern of movement approximates a point-source solution of the underlying population dynamics. A method of point sources (Green functions) is invoked for representing the solution of the tagged and untagged fish field equations (partial differential equations) in terms of integral equations. As an approximate representation of a tagging experiment, the Green function is interpreted as the probability density of survival and movement from point to point in space-time. The Green functions are constructed empirically using one parameter, catchability, as the ratio of population density of tagged fish divided by the number of tagged fish released. The number of tagging experiments necessary to characterize the population is dictated by the dependence of catchability on space-time. The moments of the Green function are used to calculate model parameters and lead to the identification of a closed form expression for the transition probability densities of the model assumed.

It is designed to address the problem of local calibration of the latter type of algorithm without recourse to high-quality ground data, which are frequently not available. A PR daily rainfall estimation method based upon the Bristol polar-orbiter effective rainfall monitoring integrative technique algorithm is described and evaluated.

Annual snow cover extent over the last 19 years decreased up to 6 x 10 super(5) km super(2) relative to a 0.93 degree C (0.33 degree C) increase in North American (Northern Hemisphere) temperature. A strong correlation exists between snow cover and temperature where up to 78% of the variance in regional snow cover and snowfall is explained by the anomalies of monthly mean maximum temperature. Over the last two decades the decrease in snow cover during winter (December-March) has largely occurred through reduced frequency of snow cover in areas that typically have a high probability of snow on the ground with little change in the frequency of snow cover in other areas. Similar characteristics were observed during spring (April-May) in areas with high snow cover probability except for an expansion of the snow-free regions. Anomalies in these two seasons dominate the interannual variability (nearly three-fourths of the variance) of snow cover. The apparent unprecedented global warmth of the 1980s was accompanied by a retreat of the mean annual North American snow cover, a 10% increase in annual Alaskan precipitation, a significant decrease (-7%) in annual snowfall over southern Canada (while the total precipitation remained above normal), and a more than twofold increase in the variance of the ratio of frozen to total precipitation over the contiguous United States. An increase (4%-5% per decade) of both solid and total precipitation over northern Canada (zone 55 degree -70 degree N) occurred during the last four decades. A century-scale increase (1% per decade) of precipitation was found over southern Canada, but the proportion of the precipitation that falls in frozen form over this area decreased over the last four decades. Precipitation over the contiguous United States has significantly (2%-3% per decade) increased during the last four decades, but on a century time scale the increasing trend is not yet statistically significant.

One method measured NO by conversion to NO sub(2) with a CrO sub(3) converter and NO sub(2) detection by luminol chemiluminescence. The other technique detects NO directly via NO/ozone chemiluminescence. The techniques were tested with a glass manifold system by addition of NO and other trace gases into a flowing zero air gas stream; water vapor was also added to the carrier gas in some cases. A second set of tests involved the simultaneous determination of NO concentrations from a chamber placed over the soil. Finally, flux measurements were made independently from common plots and from different plots within the same field. This comparison demonstrates that flux spatial heterogeneity can overwhelm analytical uncertainties, and that large sample sizes are needed to accurately characterize field fluxes.

In the present study the NOAA/ERL Wave Propagation Laboratory Doppler lidar documented such a feature, a canyon drainage jet, that extended over the adjacent plains but escaped detected by a rather dense network of surface and upper air instruments. The spatial variability in this case was dominated by the jet, which had horizontal dimensions of 1-3 km and which reached maximum speeds ) 600 m above the terrain. These features also varied significantly in time, with major changes in the structure of the jet occurring over time periods of 30-45 min. This implies that the observation-based wind field that would be used to determine real-time dispersion of atmospheric pollutants for emergency response would be in error without high resolution observations such as those from the lidar.

Estuarine watershed population estimates are presented for the following estuaries: Charlotte Harbor, FL; Tampa Bay, FL; Apalachicola Bay, FL; St. Andrews Bay, FL; Choctawhatchee Bay, FL; Pensacola Bay, FL; Perdido Bay, AL; Mobile Bay, AL; Calcasieu Lake, LA; Sabine Lake, TX; Galveston Bay, TX; Matagorda Bay, TX; San Antonio Bay, TX; Aransas Bay, TX; Corpus Christi Bay, TX. These estimates are for the years 1960, 1970, 1980, 1990, 2000, 2010. The methodology and data sets used to develop the estuarine watershed population estimates can be applied to most estuaries in the contiguous United States. A series of estuarine comparators (density per land area; per capita estuary volume) are developed from the watershed population estimates in order to underscore the utility of basin-wide comparators.

Fewer chinook salmon and adult coho salmon O. kisutch were caught with circle hooks than with J hooks. Large J hooks caught more large chinook salmon than did small J hooks, but the difference was not significant (P = 0.10). Large plugs caught significantly (P < 0.05) larger chinook salmon and fewer coho salmon and sublegal (<66 cm fork length) chinook salmon than other lures tested. Wound distribution on chinook salmon varied (P < 0.05) with hook type; circle hooks lodged in the periphery of the mouth more frequently than did J hooks. Results indicate that, in a directed coho salmon troll fishery, the use of circle hooks could reduce incidental mortality of chinook salmon but would substantially reduce coho salmon catch rate. In a quota-limited chinook salmon fishery, large plugs could be used to harvest larger fish selectively, thereby reducing encounters with sublegal fish.

Groups of fish were fed either the phosphorus-sufficient or the phosphorus-deficient diets alone, or together in various combinations during each two-week feeding period. The combinations consisted of feeding the phosphorus-sufficient diet 50, 33, 20, and 10% of the feeding days, with the phosphorus-deficient diet being fed on the other days. At the end of eight weeks, all groups were switched to the phosphorus-sufficient diet for three additional weeks. Fish were removed from each dietary treatment group for whole body proximate and elemental analysis at the beginning of the feeding trial, at two-week intervals during the first eight weeks of feeding, and at weekly intervals during the final three-week feeding period. Clinical signs of phosphorus deficiency appeared in the groups of fish receiving only the phosphorus-deficient diet after five weeks of feeding, and included lethargy, reduced growth, anorexia, and dark coloration. Fish fed the phosphorus-sufficient diet 10% of the feeding days showed signs of deficiency after 7 weeks. None of the other dietary treatment groups exhibited clinical signs of phosphorus deficiency. Periodic feeding of the low-phosphorus diet reduced whole body phosphorus levels in the fish at rates proportional to the total phosphorus fed during the eight-week trial. Whole body levels of phosphorus increased in all dietary groups during the three-week repletion period, except in the group receiving the phosphorus-sufficient diet continuously. The results of this study provide information on rates and consequences of reduction of whole body phosphorus in rainbow trout, and indicate that periodic feeding of phosphorus-deficient diets might represent one means of reducing phosphorus levels in hatchery discharge waters.

The Program has funded investigations by state management agencies, colleges, and universities, in addition to several workshops and symposia. Thirty three peer-reviewed projects, at an average funding level of $88,400, have been awarded on a competitive basis since 1990. Several of these studies are exploring the potential factors responsible for the demise of the eastern oyster in Chesapeake Bay. Work has been conducted on topics such as disease transmission and resistance, diagnostic techniques, environmental modeling, and a social/economic assessment of the oyster industry. Funding complements Federal financial support for oyster research from other sources including Sea Grant, the National Coastal Resources Research and Development Institute, and the U.S. Department of Agriculture. The NMFS Program is unique in that it requires coordination of research and management projects with the concerned State fishery agencies responsible for shellfish management. Accordingly, the Program promotes the use of scientific findings and state-of-the-art biotechnology in the development of practical approaches for state authorities to manage eastern oysters impacted by disease in Atlantic coastal waters. An overview of completed projects, currently funded research, and the current status of the Oyster Disease Research Program will be presented.

Deposition characterization AN - 16802866; 3750602 AB - Methods are discussed for describing patterns of current wet and dry deposition under various scenarios. It is proposed that total deposition data across an area of interest are the most relevant in the context of critical loads of acidic deposition, and that the total (i.e., wet plus dry) deposition will vary greatly with the location, the season, and the characteristics of individual subregions. Wet and dry deposition are proposed to differ in such fundamental ways that they must be considered separately. Both wet and dry deposition rates are controlled by the presence of the chemical species in question in the air (at altitudes of typically several kilometers in the case of wet deposition, and in air near the surface for dry). The great differences in the processes involved lead to the conclusion that it is better to measure wet and dry deposition separately and combine these quantifications to produce "total deposition" estimates than to attempt to derive total deposition directly.

The model vorticity field at the beginning of an assimilation period is adjusted to minimize a cost function that is defined as the squared difference between the model vorticity and the vorticity from a sequence of analyses separated by 12 h. After the cost function is minimized, the model vortex closely follows the observed storm track during the assimilation period, indicating that information about the past track of the storm is being included in the model solution. Track forecasts using the assimilation procedure are compared with control forecasts where the model is initialized with a single analysis at the end of the assimilation period. Results from a series of 18 forecasts for Hurricane Hugo (1989) show that with a 12-h assimilation period the average track forecast errors are smaller than those of the control forecasts out to about 48 h. The forecast errors using a 24-h assimilation period are larger than the errors with a 12-h assimilation period. JF - Monthly Weather Review AU - DeMaria, M AU - Jones, R W AD - U.S. Dep. Commer.

Hazardous freezing rain often affects the same region in winter. Conventional observations and numerical models generally are resolved too coarsely to allow detection or accurate prediction of these mesoscale severe weather phenomena. The Lake Ontario Winter Storms (LOWS) Project was conducted to demonstrate and evaluate the potential for real-time mesoscale monitoring and location-specific prediction of lake-effect storms and freezing rain, using the newest of available technologies. LOWS employed an array of specialized atmospheric remote sensors (a dual-polarization short wavelength radar, microwave radiometer, radio acoustic sounding system, and three wind profilers) with supporting observing systems and mesoscale numerical models. An overview of LOWS and its initial accomplishments is presented.

Mean and maximum latitude of occurrence of the species were regressed against average surface- and bottom-water temperatures and indices of relative abundance from spring and autumn trawl surveys. Significant (P less than or equal to 0.05) regression models were fitted for 17 of 36 species from spring and fall survey data. Variations in water temperature were significant in explaining changes in mean latitude of occurrence for 12 of 36 species in both seasons. Maximum latitude distribution responses to interannual differences in water temperature occurred for pelagic species, including Atlantic mackerel Scomber scombrus and Atlantic herring Clupea harengus. Weighted mean catches of these species shifted poleward by 0.5-0.8 degree of latitude for each 1 degree C increase in average water temperature. Statistically significant poleward range extensions, associated with warmer temperatures, occurred for five species in spring surveys and four in fall surveys. Different responses among species to changing thermal regimes of the northwest Atlantic Shelf have important potential consequences for trophic dynamics and fisheries yields of the ecosystem. Species found to be sensitive in distribution to temperature change include primary prey species of some predators that show limited seasonal or annual changes in distribution. Changes in distributional overlaps between some predators and prey therefore are a likely result of shelf warming associated with climate change.

Calculated areal excretion rates were then compared to sediment-water nitrogen fluxes measured in benthic bottom lander chambers at similar stations to estimate the potential importance of macroinvertebrate excretion to sediment nitrogen mineralization. Excretion rates for individual crustaceans (amphipods and decapods) was 2-21 nmoles NH sub(4) super(+)/(mg dry weight)/h. The mean excretion rates for the polychaetes, Paraprionaspio pinnata [6-12 nmoles NH sub(4) super(+)/(mg dry weight)/h] and Magelona sp. [27-53 nmoles NH sub(4) super(+)/(mg dry weight)/h], were comparable or higher than previous measurements for similar size benthic or pelagic invertebrates incubated at the same temperature (22 plus or minus 1 degree C). Although the relatively high rates of excretion by these selective feeders may have been partially caused by experimental handling effects (e.g., removal from sediment substrates), they probably reflected the availability of nitrogen-rich food supplies in the Mississippi River plume. When the measured weight-specific rates were extrapolated to total areal biomass, areal macroinvertebrate excretion estimates ranged from 7 mu mole NH sub(4) super(+) m super(-2)/h at a 40-m deep station near the river mouth to 18 mu mole NH sub(4) super(+) m super(-2)/h at a shallower (28-m deep) station further from the river mouth. The net flux of ammonium and nitrate from the sediments to the water measured in bottom lander chambers in the same region were 15-53 mu mole NH sub(4) super(+) m super(-2)/h and -25-21 mu mole NO sub(3) super(-) m super(-2)/h. These results suggest that excretion of NH sub(4) super(+) by macroinvertebrates could be a potentially important component of benthic nitrogen regeneration in the Mississippi River plume-Gulf shelf region.

Of 3,032 individual turtles sighted, 176 (5.8%) were accompanied by a total of 412 birds of 13 species, with three species of boobies accounting for 63% of the associated birds. The mean number of birds per associated turtle was 2.3 (S.D. = 9.63; range 1-125); single birds occurred with 82% of the associated turtles. Seabirds utilized turtles the same way they used other floating objects on the ocean, i.e., as roosting platforms and to feed on fish that aggregated beneath them. Larger flocks (i.e., > 5 birds) occurred with turtles only when the turtles were associated with flotsam and schools of predatory fish; in each of these cases birds foraged over the fish and appeared to be only incidentally associated with turtles. The olive ridley (Lepidochelys olivacea) is by far the most abundant sea turtle of the five species that occur in the ETP and the only species observed with associated birds. Although millions of olive ridleys have been harvested in the ETP over the past several decades, it is still an abundant species and continues to represent a small but contributing resource for foraging seabirds, especially boobies.

Lengths at early ages back-calculated from younger age-groups sometimes are greater than lengths at the same age estimated from older age-groups, referred to as Lee's phenomenon. Lee's phenomenon can be simulated with use of size-selective mortality and moving averages to incorporate error dependency in lengths at age. To evaluate the appropriateness of using back-calculated lengths at formation of all annuli in growth analyses when size-selective mortality is present, we used simulated data based on von Bertalanffy growth parameters and total mortality for red grouper Epinephelus morio from the southeastern U.S. Atlantic coast. Asymptotic length (L arrow left ) and the growth coefficient (K) showed greater bias when estimated with back-calculated lengths at all annuli than when estimated only with back-calculated lengths at the most recent annuli whenever Lee's phenomenon (or its reverse) was present. One should use only lengths back-calculated to the most recent annuli when estimating growth parameters representative of a population.

Results from changing only first-year survival rate (S sub(o)) have already been published (Schaaf et al. 1987). This paper explores the effects of perturbing both S sub(o) and the adult survival rate (S sub(i)) for 12 spatial-temporal stocks. Most stocks examined are more sensitive to permanent change in S sub(i) than to changes in S sub(o). The relative importance of these two rates in determining the population growth rate ( lambda ) depends upon the age distribution of the expected lifetime egg production of age i females (V sub(i)). In turn, the vector V sub(i), as measured by its mean and standard deviation, is shown to vary among geographic or temporal stocks of a single species. Hence, we quantify the impact on population size of destroying a fixed percentage of habitat, relative to where and when it occurs (i.e., relative impact on S sub(i) and S sub(o)). For example, destroying 1% of the Atlantic menhaden habitat would reduce lambda by 0.8% and the population by 8.0% in 10 yr, if the impact affected only adults (e.g., offshore in winter). If the 1% habitat destruction all occurred in the estuaries, affecting juveniles as well, lambda would be reduced by almost 5%, and in 10 yr drive the population down to 58% of its former equilibrium. We show that knowledge of the mean and variance of the age distribution of V sub(i) permits prediction of relative sensitivity among species to pollution. Within species, this knowledge of V sub(i) permits comparison of the effects of impacting different life stages, and at different times and places.

Prevalences of a number of pathological conditions, including neoplasms, preneoplastic lesions, hydropic vacuolation, and other necrotic and proliferative lesions, were significantly elevated in fish from contaminated urban embayments such as Boston Harbor and Raritan Bay. Results of logistic regression analyses indicated that polycyclic aromatic hydrocarbons, DDTs, or chlordanes in sediments, stomach contents, liver, or bile of winter flounder were significant risk factors for the development of several lesion types, including hydropic vacuolation and proliferative and necrotic lesions.

The expedition was sponsored by the Intergovernmental Oceanographic Commission (IOC), Regional Organization for the Protection of the Marine Environment (ROPME), United Nations Environmental Programme (UNEP), U.S. National Oceanic and Atmospheric Administration (NOAA), and the Marine Spill Response Corporation (MSRC) and focused on the fate and effects of the 1991 Gulf war oil spills on the region's marine environment. The expedition was unusual, given the limited time in which it was conceived, planned, implemented, and completed. The mission's success may be measured not only in the wealth of scientific data collected, but also in the strides made in local, regional, and international environmental awareness and political cooperation in the Gulf.

Water temperature and salinity patterns observed in 1992 are compared to 1978 through 1991 means within a time-space matrix. The objective is to monitor changes in the U.S. Northeast Shelf Ecosystem in relation to possible effects on the long-term sustainability of fishery yields of the system (Sherman et al, 1988). Reports describing the water column and bottom temperature conditions along these two routes are prepared annually, and were summarized through 1990 in Benway et al. (1993). This report presents surface temperature and salinity, and bottom temperature conditions along the Middle Atlantic Bight and Gulf of Maine transects during 1992 and describes their departures from average conditions for the fourteen-year period, 1978 through 1991.

A commercial diet was fed as a reference standard. The diets were fed to duplicate groups of fish (initial weight 3.6 g) for 8 weeks. The egg white and blood fibrin diets had low palatability. The percent weight gain, PER, PPV (%), and feed efficiency (weight gain/feed fed) of the casein diet were: 262, 2.63, 40.7, and 1.50. These parameters did not differ from those of the isolated fish meal protein or the commercial diet, indicating that casein can be used as the basal protein source in semi-purified test diets for juvenile Atlantic salmon.

Nonetheless, dry conditions returned to sub-Saharan West Africa (10 degree -20 degree N). After two years of near-average rainfall, relative to the last 50 years, this region experienced its second driest April-October since the record drought years of 1983-84. This was the eighth driest April-October period in at least the past half-century. The remainder of the Northern Hemisphere summer monsoon regions experienced mixed seasons, with the Indian summer monsoon rainfall appearing to be about normal overall. The summer monsoon season in China started with excessive rainfall amounts, but closed dry in southern areas. Dry conditions also prevailed in the southeastern United States and over most of western Europe. JF - Journal of Climate AU - Ropelewski, C F AU - Lamb, P J AU - Portis, D H AD - NOAA/Clim. Anal.

Mesocosms isolated emergent macrophytes (Pontedaria sp.), floating macrophytes (Lemna sp.), sediments, and plankton. Experiments were performed by enriching concentrations of nitrate (NO sub(3) super(-)), ammonium (NH sub(4) super(+)), and phosphate (PO sub(4) super(3-)) to levels between 0.5 and 1.5 mg/l, and then following changes in the concentrations over time. Plant mesocosms produced the highest removal efficiencies averaging 67, 87, and 62% per day for NO sub(3) super(-), NH sub(4) super(+), and PO sub(4) super(3-) respectively. However, removal efficiencies for sediment mesocosms averaged 52, 59, and 49% per day respectively indicating that much of the removal processes may have occurred at the substrate surface. In all mesocosm treatments, PO sub(4) super(3-) was removed at a much greater rate than needed to meet biological demands, and nutrients were removed at nearly the 2:1 N:P mass ratio in which they were added. Removal rates in mesocosm experiments were compared to rates calculated by mass balance for a storm which generated 12 days of flow through the marsh. Mesocosm results agreed closely with mass balance calculations for NO sub(3) super(-) and PO sub(4) super(3-) but did not agree with NH sub(4) super(+) calculations. NH sub(4) super(+) concentrations in the stormflow were too low and removal rates for NH sub(4) super(+) may have been affected by internal production within the marsh.

Almost without exception, the studies published up to 1990 have shown that sediment contamination increased in the late 1800s, accelerated in the 1940s, and reached a plateau or a maximum in the 1960-1970s. For some pollutants, such as Pb, a decrease in concentration occurred in the 1980s, following the implementation of new discharge and emission regulations. Little is known, however, about concentration trends from the mid-1980s to present and about the effect of legislation recently passed to protect the environment. JF - Estuaries.

Net economic value could be maximized by an estimated 70% reduction in fishing effort, resulting in a sevenfold increase in the size of the harvestable resource and a threefold increase in sustainable yield. Under these conditions, fishers, seafood industries, and consumers could benefit from an estimated US$150 million increase in sustainable net economic value each year, including about $130 million in resource rent. Consumers in the region could profit further from the nutritional and health benefits of up to an additional 6 lb of fresh fish per capita. Policies to achieve these benefits are highlighted. Augmenting state ownership of the resource with market transfers of individual effort or harvest quotas is preferred to open access, but common property or individual private property regimes are more likely to benefit society.

These measurements, taken during a 21-day on-site period of the Tropical Instability Wave Experiment (TIWE), constitute the first comprehensive database for examining subgrid-scale parameterizations of cloud and radiation interactions for nonhomogeneous cloud regimes. The high-resolution field experiment data are used in combination with satellite-based records to investigate the relationship between small-scale (temporal and spatial) quantities and the large-scale parameterizations of the effects. In the 21-day ship-based record the average cloud fraction was 0.26 and the average cloud optical depth was about 2. The temporally averaged ship-based estimate of cloud liquid water for this period was 54 g m super(-2), and the temporally averaged satellite-based estimate of cloud liquid water within 25 km of the ship was 50 g m super(-2).

The Mussel Watch Project was extended in 1992 to include seven sites in the U.S. Great Lakes' waters from Saginaw Bay to western Lake Erie. Zebra mussels (Driessena polymorpha) were collected at each site with three samples of approximately 250 large specimens selected for analysis from each of the five sites where sufficient material was obtained. At the two remaining sites only enough material for one set of analyses was available. The concentrations of 60 organic contaminants including 24 PAH compounds, 20 PCB congeners, DDT and its metabolites, and 9 other pesticides were quantified for these samples. The level of some of these toxic contaminants clearly differed among sites and usually ranged over a factor of at least three. The highest concentrations were generally found at sites in proximity to the Detroit (Grosse Ile) and near the mouth of the Saginaw River, with the lowest concentrations found in lower Lake Huron and the Reno Beach area of western Lake Erie. The contaminant levels quantified in Great Lakes zebra mussel tissues fall within the ranges found in bivalve tissues at U.S. marine sites. The levels of total PCBs at Grosse Ile, Put-in-Bay, and the Saginaw River were found to be relatively high on a national basis (i.e., greater than one standard deviation above the national mean) as was the total PAH level at Grosse Ile.

During the summer months of intense water density stratification, exaggerated responses of thermocline displacement and associated currents occurred during intervals of wind forcing at periods close to the bay's free internal seiche period. The seiches were of relatively small amplitude at the ends of the basin, but caused currents energetic enough to be important in water volume fluxes between the north and south halves of the bay past the Chambers Island constriction. In contrast to the Green Bay seiches, which are heavily damped by bottom friction in the shallow bay, internal seiches that we have observed during 1991 and 1992 in the deep and narrow Lake Champlain basin attain very large amplitude when the period of wind forcing is near that of the seiche. We compare the near-resonant seiche generating processes in the two lake basins and discuss their relative importance in the dynamics of each.

S. National Oceanic and Atmospheric Administration and the Canadian Hydrographic Service. This bathymetry has been constructed using the entire archive of historic hydrographic data assembled since 1903 in the U.S. and Canada. Details of bottom configuration for the shallow (<12m) western basin of Lake Erie are highlighted using a one-meter contour interval. Sedimentary strata overlying bedrock record a history of post-glacial deposition at lake levels both lower and higher than present levels. The surficial and most recent sediments are predominantly fine sands and silts (muds) deposited during the last 4000 years, a time when lake level was about the same as it is at present. Wind-driven water circulation has formed sedimentary relief features in western Lake Erie; overdeepened channels between islands have resulted from intensified movement of water through these restricted passages. Gently sloping lower-relief ridges are probably sediment drifts whose position is related to patterns of water circulation. Channels are revealed on the floor of the western Lake Erie basin underlying the main shipping lanes in water depths exceeding the dredged channel depth limit of 8.5 meters. These channels have probably been excavated by propeller wash in the open sea lanes where ship traffic increases speed, resulting in intensified scour.

An automated methodology was used to obtain higher spatial resolution than previously obtained. The increase in resolution was attained by using all available monthly snowfall data from over 1230 stations per year combined with a monthly time step to produce high-resolution grids. These monthly grids were combined to produce snow-year grids. Multiyear average grids were created and compared. This technique minimizes traditional problems associated with missing data and variable length station records. The three 10-year average distribution maps presented here indicate a period of increasing snowfall. Windowing of the 30 seasonal grids revealed that increasing snowfall was attributable to an increase in lake effect snowfall and not to continental snowfall. The Great Lakes drainage basin was evaluated for trends within and between monthly and seasonal average snowfall through windowing of all 240 monthly grids. The graphical and statistical evaluation of these trends indicates a strong natural variation in the region's snowfall and reveals an increasing trend during the study period.

The rate of ozone decrease during formation of the springtime ozone hole and the severity of ozone loss in the lower stratosphere were greater in 1992 as compared to previous years. Total ozone reached an all time low of about 105 Dobson units on October 11 at South Pole Station. On this day, the balloon-borne instrument encountered an apparent ozone void between altitudes of 14 and 18 km. Ozone profiles showed evidence of unusual ozone depletion in autumn, before polar stratospheric cloud existence temperatures were reached. Satellite measurements indicated that the 1992 ozone hole was about 25% larger in geographical extent than in previous years. The possible effects of the eruption of the Pinatubo volcano in the Philippine Islands in 1991 are investigated, and it is concluded that the sulfuric acid droplets, which formed in the stratosphere following the eruption and were trapped in the south polar vortex, are the most likely source of the anomalous Antarctic ozone depletion in 1992.

The daily normal temperature of each of the Great Lakes was derived from remotely-sensed data acquired by the Canadian Atmospheric Environment Service and NOAA's IMGMAP program. We extrapolated the results to a Mercator projection with a 2.5 km grid resolution. Normal ice cover maps, from the NOAA Great Lakes Ice Atlas, were interpolated to yield daily patterns and converted to the same projection. The two-dimensional surface temperature and ice data, bathymetry maps, and normal daily vertical temperature profiles, were combined into a database for an analysis and animation program. This interactive, menu-driven computer program, for an IBM compatible PC with color VGA graphics adapter, has four main modules for data presentation: a) normal daily surface temperature and ice patterns, b) horizontal surface temperature and ice cover profiles, c) daily mean vertical temperature depth profile and d) surface temperature and ice cover versus bathymetry. All modules display daily normal values in animated sequences. Online documentation of the program and the data set is provided. The two-dimensional data (module a) are presented in color-coded maps, while modules b, c and d provide plots. The animations can be manipulated interactively and actual temperature and ice values, along with geographical location or depth, can be accessed and displayed numerically with a mouse-driven cursor. The dependence of temperature and ice cover upon bathymetry can be investigated in two manners: 1) by toggling between the spatial temperature pattern and bathymetry and 2) by viewing plots of temperature or ice versus depth.

The composition of surface waters (river, lake, and coastal) has changed over time. Well known at present are the changes due to the Industrial Revolution, dating from the middle of the last century. These changes are expressed by increased levels of natural components like heavy metals, polyaromatic hydrocarbons (PAHs), nutrients, and additionally, since the start of this century, xenobiotic compounds like polychlorinated biphenyls (PCBs) and pesticides. Since the early 1960s, regulatory measures have been taken to decrease the amount of pollutants entering our waterways. Because of a lack of data, the extent of past pollution and the effect of recent limitations is often difficult to assess. Before the 1960s, metal and nutrient research was mainly an academic exercise and surface waters were not analyzed on a regular basis. In addition, the analytical methods necessary to analyze the various chemicals entering our waterways, in particular, organic compounds, did not exist. The analysis of sediment cores presents a way out of this dilemma. JF - Estuaries. 1993.

Normal spatial lake surface temperatures and ice cover of each of the Great Lakes, except Lake Michigan, were calculated using remotely sensed data. These results were subsequently used for calculating the normal energy flux patterns at the water surface in the following manner. For each day of a 30-year period, mean surface temperatures were modeled with a one dimensional energy-flux model. Daily spatial temperature patterns were derived by adding the difference between the modeled mean and the average of the normal temperatures to the normal spatial temperature pattern. Meteorological parameter patterns were modeled by weighting the meteorological measurements, which were corrected for overlake conditions, by the inverse square distance of each gridpoint from the measuring site. The energy fluxes (shortwave radiation, net longwave radiation, latent and sensible heat flux) were calculated for each day and gridpoint, and an average value for each day of the year was calculated from the 30-year period. Long-term energy fluxes should balance; indeed the 30-year average is within plus or minus 2.5 W/m super(2) on all lakes, except Superior. The energy balance patterns apparently are determined primarily by evaporation. In the spring, ice cover contributes significantly to energy balance patterns due to its large impact upon shortwave radiation. Surface temperature is an integrated expression of past meteorology and changes more slowly than meteorology. We observed that the patterns of net longwave radiation and sensible and latent heat were more similar to temperature patterns than to meteorological patterns. Therefore knowledge of water surface temperature patterns is crucial to determine energy flux patterns.

Data, consisting of deposition measurements at Shaartuz, atmospheric columnar mass, aerosol concentrations, wind speed, optical scattering, and movement of soil, were collected for the dust storms of 16 and 20 September 1989. Results from the model were compared with measurements of total atmospheric columnar mass loading for the dust storm of 16 September. Although sensitivity of the model to dust layer height does not recommend the model for general use, the model has some merit in predicting transport and deposition for dust contained in a river valley.

In each of these years, divers collected replicate samples at each of 29 stations located throughout the lake. In 1986, prior to discovery of the zebra mussel, unionids were found at 25 of 29 stations. While the number of stations with unionids remained at 25 in 1990, the number had decreased to 13 in 1992. In general, no unionids were found at stations located southeast of the shipping channel in 1992. In 1990, unionids in this portion of the lake had the highest number of attached mussels. Although present in 1992, unionids at stations in the northwest portion of the lake were infested with attached mussels at mean densities of 4-229 mussels per unionid at an individual station. In contrast, zebra mussels were rarely found on unionids in this portion of the lake in 1990. Thus, based on the occurrence of events between 1990 and 1992, unionids might be expected to be eliminated from open waters of the lake in 2-3 years.

Potential uptake rates peaked in September and corresponded closely with chlorophyll concentrations. The presence of zebra mussels in the bottles (15 per 4-liter bottle) removed some phytoplankton and sometimes caused potential uptake rates to decrease. Ammonium regeneration rates, in the absence of zebra mussel, followed similar seasonal patterns but, as expected, were lower than potential uptake rates. Community ammonium regeneration rates were consistently increased by the presence of zebra mussels indicating that zebra mussel excretion is an important contributor to ammonium regeneration in regions where the bivalve is abundant.

Observers from each nation were hired, trained, and deployed to high seas driftnet vessels to conduct scientific monitoring and data gathering.

The experimental design consisted of four-liter bottles containing Saginaw Bay water treated with zebra mussels or held as controls. In associated with bacterial analysis, additional bottles were treated with epifluorescing polystyrene beads of 0.91 mu m and 0.22 mu m diameter to determine size selective grazing of bacterial size particles. Representative samples were collected and preserved from the bottles periodically for twenty hours. Bacterial abundance did not differ significantly between zebra mussel treatment and controls although the relative size of the individual cells did appear to be smaller in the presence of zebra mussels. In July, abundances of large beads progressively decreased over time in the presence zebra mussels whereas those of small beads were not effected. These results suggest that zebra mussels may remove large bacteria from the water, but do not significantly affect smaller sized bacteria.

Physico-chemical characteristics of deposited dust were compared with those of soil-derived dust collected in other regions. Particle mass-size distributions appear to be characterized by a common log-normal mode between 1 and 10 mu m. Chemical composition of the sampled material shows that the dust is particularly rich in calcium and silicon and poor in iron. Estimated mineral composition of dust indicates that this enrichment in Ca and Si for the Soviet Asian dust must be related to high contents of carbonate and quartz, respectively. Different Fe/Al also suggest a specific chemical composition for clay minerals in the Asian dust. JF - Atmospheric Environment; Part A, General Topics AU - Gomes, L AU - Gillette, DA AD - Air Resour.

In the first study, two subtidal marsh creeks were sampled with weirs from April-November 1988 (n = 42) and seines from July-November 1988 (n = 33), while in the second study two intertidal creeks were sampled with weirs from July-October 1989 (n = 28). Fish and decapod species assemblages captured in subtidal weir, subtidal seine and intertidal weir, as measured by both relative abundance and canonical discrimination analyses, were all highly affected by diel period. Total abundance and abundances of 15 species of fish and decapods exhibited significant diel differences, some of which were strongly influenced by season and life history stage (i.e. size cohorts). A detailed examination of the most abundant species, Menidia menidia, reveals that adults were more abundant during the day in early summer, suggesting diurnal reproductive movements into the creeks. In contrast, young-of-the-year cohorts were significantly more abundant at night during the late summer and fall, suggesting nocturnal movement into shallow marsh creek habitats. Our observations of strong diel differences in species assemblages point out the need for both day and night sampling in marsh habitats, if the importance of these habitats to fishes and decapods are to be fully understood.

The northern offshore and southern offshore stocks were compared because both have been exploited by the yellowfin tuna purse-seine fishery, but at different rates. We predicted decreasing trends in the ASM and increasing trends in the ASM and increasing trends in the pregnancy rate for each stock because both have declined in abundance. A lower ASM and a higher pregnancy rate were predicted for the sample from the northern offshore stock because it has been exploited to a greater extent than the southern offshore stock. No statistically significant trends were found in the ASM, but the increase in the proportion of sexually mature females simultaneously pregnant and lactating for the northern offshore stock and the decrease in the proportion of mature females in the population for the southern offshore stock over time were statistically significant. The mean estimate of ASM was significantly higher for the northern offshore stock, 11.1 years (SE=0.236), than for the southern offshore stock, 9.8 years (SE=0.264). No significant differences between stocks were found in the mean estimates of reproductive parameters. Our analyses of temporal trends in several biological parameters did not provide conclusive evidence for compensatory responses having occurred, and therefore some possible explanations are considered.

Multiple photographs were taken of 48 separate schools during a 1989 eastern tropical Pacific (ETP) dolphin abundance survey. During a 12-week "counting period," three readers did independent counts of dolphins in the photographs. For each school, the best photograph imagery was selected and the mean of the three independent counts was used to estimate its "true" size. The coefficient of variation (CV) for school size estimates (between-reader precision) averaged 5.4% and ranged between 1.2% and 14.6%. Most (92%) of the schools were estimated with precision, resulting in a CV of less than 9.0%. Within-reader CV averaged 3.5% and ranged 1.4%-7.1%, indicating that readers were quite precise. To test if reader methods were constant during the counting period, temporal trends in estimates were tested by linear regression analyses and a repeated-counts experiment with repeated measures analysis of variance (RM-ANOVA). Regression analyses indicated no significant temporal trends or bias in the deviation of counts from the means. The RM-ANOVA showed a significant "reader with time" interaction which was attributed to the relatively high variability between readers in counts made at the start of the experiment. Results suggested that methods were constant and counts were precise after an initial "warm-up" counting session. JF - Fishery Bulletin AU - Gilpatrick, JW Jr AD - Southwest Fish. Sci.

Simultaneous tows of bottom and surface 1 m, 500 micron mesh nets were made day and night at single stations inside of Oregon Inlet and Ocracoke Inlet. Oregon Inlet, located in a more temperate marine province, was expected to have a different taxonomic community than Ocracoke Inlet, but, of 77 taxa collected from both inlets, 54 occurred at both inlets. Clupeoids and sciaenids were the dominant taxa in both inlets. At Oregon Inlet the lowest abundance of larvae occurred in February and the highest occurred in late August, whereas at Ocracoke Inlet, November and June were the lowest and highest months of larval abundance. At Oregon Inlet, 63% of the total number of larvae were caught near the bottom, but at Ocracoke Inlet, only 38% were caught near the bottom. Atlantic menhaden, Brevoortia tyrannus, were 40 times more abundant at the surface than at the bottom at Ocracoke Inlet. Most larvae were caught at night at both inlets. The times of occurrence and peak abundance for most species did not appear linked between inlets. Twenty-one species were significantly different in mean length between the two inlets.

Results from this simulation study provided a basis for subsequent U.S. legislation regarding criteria for comparing dolphin mortality rates of U.S. vs. non-U.S. fleets fishing in the ETP, pursuant to regulations governing import of tuna from this area. Accuracy and precision of mortality estimates were influenced very strongly by data quality (dolphin group type) and moderately strongly by fleet size and level of observer coverage. Because neither fleet size nor dolphin group type can be controlled by a sampling program, desired levels of accuracy and precision in estimates of dolphin mortality can be achieved only by manipulating the level of observer coverage. The unexpectedly strong effect of dolphin group type implies that to protect all groups equally, observer levels should be chosen to accommodate the dolphin group type exhibiting the poorest-quality data.

AN - 16735844; 3719177 AB - Benthic amphipods, Diporeia sp., were collected during 1988 and 1989 at two sites in Lakes Michigan and Ontario to compare size and lipid levels of animals living in different locations. Collection sites were at depths of 45 m and 100 m in Lake Michigan, and 35 m and 125 m in Lake Ontario. Dry weight, length, total lipid, and lipid class composition was determined for individual amphipods. In Lake Michigan Diporeia sp. from the 45 m depth had higher dry weights, were longer in length, and contained more lipids than those individuals collected at the 100 m site. This pattern was similar in both 1988 and 1989. In contrast, Lake Ontario Diporeia sp. generally weighed more and had higher lipid levels than Lake Michigan animals regardless of collection depth, except in 1989 at the 125 m site where lipid levels declined from the previous year, although dry weight and length remained the same. Triacylglycerols were the dominant lipid class in all the amphipods with levels reaching a maximum of 88% of the total lipid in individuals from Lake Ontario at 35 m.

N1 - Last updated - 2014-05-06 ER - TY - BOOK T1 - A guide to planting seagrasses in the Gulf of Mexico AN - 16729979; 3507501 AB - Seagrasses form one of the most productive plant communities on the planet. They provide valuable and virtually irreplaceable habitat for numerous recreational and commercial fishery organisms as well as their prey. Tremendous losses of this habitat have occurred in the Gulf of Mexico (and elsewhere), however, as a result of development within the coastal zone. To counter wetland losses, the Nation has adopted the National Wetland Policy Forum's (1988) recommendation of "no net loss" of wetland habitat. Seagrasses have sometimes been differentiated from wetlands because they occur primarily underwater. The well-documented ecological function and potential linkages among seagrass systems and other, more easily observed coastal plant communities, however, indicate that such a differentiation is semantic only. Seagrass habitat cannot be separated from the no net loss philosophy under any rational management strategy. Losses to seagrass habitats may be slowed or even reversed through properly planned and executed planting projects. This handbook was developed to guide agency personnel, private consultants and others involved in wetland permitting, mitigation and restoration through the successful completion of these projects. There is no easy way to plant seagrass beds and meet the goal of maintaining or increasing seagrass acreage. It is an inherently complicated process that does not lend itself to oversimplification. Such a tactic would be especially misleading to readers and seriously misrepresent the skill development and capital outlay required to develop a fully functional seagrass meadow. This, after all, is the implicit, but often unstated, goal of all seagrass plantings.

In April 1990 a site was established in Lake Michigan to continuously monitor the offshore thermal structure and vertical velocity profile. The site is located near the center of the lake's southern basin in 160 m of water. Temperature is measured at 16 depths (winter) to 28 depths (summer), and the horizontal velocity components are measured at 5 levels which allows us to characterize the offshore environment with high temporal resolution. The goals of this effort are to provide basic physical measurements to better describe the flow of energy through the lake ecosystem and to provide a basis against which future change can be better gauged.

Part III. Water budget AN - 16722462; 3509556 AB - The hydrometeor water budget of Hurricane Norbert on 24 September 1984 is computed using two microphysical retrieval techniques. Three-dimensional distributions of condensation, evaporation, precipitation, and advection of cloud and precipitation are computed, and a bulk water budget is computed as the volume integral of these distributions. The role of the microphysical retrievals is to provide the three-dimensional distribution of cloud water content, since it cannot be determined with the equipment available. Both retrieval methods use the steady-state continuity equation for water. The first method determines precipitation formation mechanisms from the radar-reflectivity and Doppler wind fields. The cloud water content is determined, through microphysical modeling, to be the amount necessary to explain the rate of precipitation formation. The second method solves the water continuity equations as a boundary value problem, while also employing microphysical modeling. This method is applied in three dimensions for the first time. Asymmetrics in the water budget of Hurricane Norbert were important, apparently accounting for nearly half the net condensation. The most condensation and heaviest precipitation was to the left of the storm track, while the strongest evaporation was to the rear of the storm. Many of the downdrafts were unsaturated because they were downwind of the precipitation maximum where little water was available for evaporation. Since the evaporation in the downdrafts was significantly less than the condensation in their counterpart updrafts, net condensation (bulk condensation-bulk evaporation) was significantly greater than would be implied by the net upward mass flux. Much of the vapor required to account for the greater bulk condensation appears to have come from enhanced sea surface evaporation under the dry downdraft air to the right of the storm track. The net outflow of condensate from the storm inner core was quite small, although there were appreciable outward and inward horizontal fluxes at certain locations. A maximum of ice outflow to the left of the storm track in the front of the storm corresponded well to the ice particle trajectories that Houze et al. suggested were feeding the stratiform precipitation found farther outward from the storm center.

This variation cannot be accounted for in conventional plume dispersion models. In this study, three random-walk models of varying complexity are formulated to simulate dispersion in katabatic flows, and their strengths and weaknesses are discussed. The flow and turbulence parameters required by these models are determined from a high-resolution two-dimensional katabatic flow model based on a turbulent kinetic energy closure. Random-walk model calculations have been performed for several values of source height and slope angle to examine the influence of these parameters on dispersion. Finally, we simulated the perfluorocarbon and heavy methane tracer releases for Night 4 of the 1980 ASCOT field study over a nearly two-dimensional slope in Anderson Creek Valley, California. The observed peak concentrations are generally well-predicted. JF - Boundary-Layer Meteorology AU - Luhar, A K AU - Shankar Rao, K AD - Atmos. Turbulence and Diffusion Div., NOAA/ARL, P.O.

Sludge dumping, even in deep ocean waters, was not discounted as one of several ecological and environmental perturbations influencing these resources measured as temporal, spatial, and seasonal differences in abundance. Species abundances of silver and red hakes (Merluccius bilinearis and Urophycis chuss), summer flounder (Paralichthys dentatus), goosefish (Lophius americanus) and black sea bass (Centropristis striata) declined significantly over temporal and spatial scales during the disposal of contaminant laden sewage sludge at the deepwater 106-MDS. There was also a decline in the array of all aggregated species, but to a lesser degree. Results of these analyses of assessment data are considered in relation to effects of ocean dumping in shallow waters at the southern California sewage outfalls and in the New York Bight apex, and in relation to increased contamination of the ecosystem around the 106-MDS. Further, large-scale coordination of environmental research surveys with fishery resource assessments would allow tests of more specific hypotheses and allow a more definitive interpretation of offshre resource population data as presented here.

These marks provide direct evidence of interactions among fisheries. U.S. trollers operating in the North Pacific have reported an increased frequency of net-marked fish with the expansion of the Taiwanese, Korean, and Japanese high-seas driftnet fleets (NOAA, 1991). Our study, part of a larger effort to determine the impacts of drift nets on the North Pacific albacore stock, was undertaken to determine whether albacore that encounter drift nets, and subsequently escape alive, suffer higher than normal rates of natural mortality.

This solution's sensitivity can be examined by comparing it to solutions derived under alternative model specifications. Four such modifications are considered here: replacing the Cushing stock-recruitment equation with an equation of the Beverton-Holt form; generalizing from linear growth to a flexible form of von Bertalanffy growth; allowing the ages of recruitment to the fishery a sub(f) and the mature stock a sub(m) to diverge; and allowing for a finite maximum age in the stock. Exact polynomial solutions for F sub(MSY) are derived for each specification (except the fourth), and the potential bias introduced by use of the base model is examined for each. In all cases, the solution to the base model is within 10% of the solution to the alternative model under a range of parameter values. JF - Fishery Bulletin AU - Thompson, G G AD - Resour. Ecol.

AN - 16703620; 3534401 AB - The shrub-steppe area near Shaartuz, Tadzhik, S.S.R., is shown to be a net accumulator of dust despite being an occasional source of dust. For the accumulation of the dust to form the observed surface crust, a net deposition of about 290-490 g m super(-2) yr super(-1) of particles smaller than 20 mu m is required, depending on the duration of the deposition period. The particles smaller than 20 mu m are mixed with particles brought up from the sandy material below the surface crust by bioturbation and are incorporated into the surface crust. Measurements during the 16 and 20 September 1989 dust storms provided a total deposition of 41.1 g m super(-2) of particles smaller than 20 mu m. Because 10-30 dust storms are observed at Shaartuz, the measured average dust storm deposition would yield 206-617 g m super(-2) yr super(-1). This range of deposition is of the order of that needed to provide a mass balance for the observed crust formation. Cryptogams (including algae, lichen, and moss) and rainwater are the main agents of incorporation of the aeolian dust into a stable soil crust.

Utilization of Kaiser's Varimax orthogonal rotation led to the delineation of six contiguous subregions or "influence regimes" which together accounted for 64.02% of the total variance. Each subregion displayed statistically unique O sub(3) characteristics and corresponded well with the path and frequency of anticyclones. When compared to the entire domain, the mid-Atlantic and south subregions observe higher mean daily 1-h maximum concentrations. Concentrations are near the domain average for the northeast and southwest subregions and are lowest in the Great Lakes and Florida subregions. The percentage of observations exceeding 120 ppb were greatest in the mid-Atlantic and southwest subregions, near the domain average in the northeast and south subregions, and lowest in the Great Lakes and Florida subregions.

In the months following the spill, over 1,000 sea otters (Enhydra lutris) from oil spill-affected areas are known to have died. The purpose of the study is to identify and describe histopathologic lesions associated with crude oil exposure in sea otters and to discuss possible pathogeneses of the lesions. Materials available included tissues from oil-contaminated and uncontaminated otters that died in rehabilitation centers following the oil spill and tissues from otters that were found dead in the oil spill-affected area with external oil present. Tissues from apparently normal sea otters from an area not contaminated by crude oil, were also examined.

AN - 16681823; 3043740 AB - Field studies on ovarian development in English sole (Parophrys vetulus ) from urban and nonurban sites in Puget Sound, Washington, USA, demonstrated that animals with elevated levels of fluorescent aromatic compounds (FACs) in bile were less likely to enter vitellogenesis and had lower plasma concentrations of estradiol than female sole with low levels of contaminant exposure. Biliary FACs were positively correlated with hepatic P450 activity, which was also elevated in sole showing inhibited ovarian development. These findings suggest that contaminant exposure may disrupt vitellogenesis in female fish. Results of the field study were supported by laboratory experiments showing that pretreatment of gravid female English sole with extracts of contaminated sediment decreased levels of endogenous estradiol. A similar response was observed in rock sole (Lepidopsetta bilineata ) and flathead sole (Hippoglossoides elassodon ) treated with Prudhoe Bay crude oil. However, exposure of English sole to sediment extracts had little effect on the activity of hepatic-steroid-metabolizing enzymes, indicating that some mechanism other than enhanced steroid metabolism may be responsible for reductions in endogenous circulating-steroid levels. Our recent studies suggest that reductions in endogenous estradiol levels may result from depressed ovarian steroidogenesis, as contaminant-associated reductions in in-vitro ovarian estradiol production were observed in English sole, rock sole, and flathead sole. Preliminary studies on winter flounder and white croaker indicate that they may also experience reproductive impairment as a result of exposure to contaminants, but the phase of the reproductive cycle that is most several impacted varies from species to species.

AN - 16681511; 3043746 AB - Our studies have shown that early stages of the reproductive process in female English sole (Parophrys vetulus ) are disrupted by contaminant exposure. To determine the potential for contaminants to affect later stages of the reproductive cycle, we examined the effects of maternal contaminant exposure on egg and larval viability in this species, in a field study conducted on running ripe fish collected for two consecutive years from spawning grounds. Maternal contaminant exposure was assessed by several methods. Stepwise multiple regression of the data showed that contaminant exposure was only a minor factor in determining egg and larval viability. However, because the range of contaminant exposure in the spawning fish did not encompass the high levels seen in non-spawning fish captured from contaminated areas, it can be hypothesized that female English sole exposed to substantial levels of contaminants might be at least partially excluded from the spawning population.

AN - 16676155; 3035937 AB - Vitellogenin (Vg) is an egg yolk precursor protein that is produced in the liver and transported to developing oocytes in the gonad by the blood. Contaminants in the environment may affect its production by the liver as well as its uptake by the gonad, threatening the development and survival of winter flounder embryos or larvae. In order to study the effects of cadmium contamination on serum Vg levels (measured as alkali-labile phosphate or ALP), female winter flounder were exposed to 25 or 50 mu g/L cadmium in seawater for 71 days. The exposure began in early November when Vg production begins, and ended in mid-January, when Vg levels peak. At the end of the exposure period, blood samples were taken from each fish, refrigerated, and allowed to clot overnight. The sera were collected by centrifugation the following day and frozen. Weights of the liver, both gonads, and the entire fish were recorded for later calculation of hepatosomatic (HSI) and gonadosomatic indices (GSI), respectively. Liver samples were also taken for measurement of cadmium levels.

AN - 16674995; 3044254 AB - Vitellogenic female English sole (Parophrys vetulus ) sampled from four areas in Puget Sound were injected with an analogue of LHRH in the laboratory to induce spawning. Ability to spawn, time to spawn, larval viability, and initial concentrations of plasma estradiol and vitellogenin (measured as alkaline-labile protein-associated phosphate (ALP)) were assessed. In general, low initial-plasma-estradiol and ALP concentrations and subsequent reproductive impairment (i.e. reduced ability to spawn and reduced larval viability) were most common in English sole from sites where levels of sediment contaminants and measures of contaminant exposure in fish were highest. Additionally, spawning and fertilization success were found to be positively correlated with initial-plasma-estradiol and ALP concentrations, respectively. Preliminary results also suggest that, although fecundity is not reduced in English sole from contaminated sites, egg size may be smaller, particularly in relation to PCB exposure. Overall, these findings suggest that contaminant exposure may result in poor reproductive success of female English sole. A similar study with rock sole (Lepidopsetta bilineata ) suggests that this species may also show reduced spawning ability, fertilization success, and egg size in conjunction with contaminant exposure.

We evaluated the possibility that chemical inhibition has a role in the apparent exclusion of the species from Great Bay, New Jersey. Two of three assays, conducted in consecutive summers, detected pronounced inhibition of Great Bay water to A. tamarense . This suggests that the bay at times can be unsuitable for the species. Assay results also suggest that availability of required metals and level of natural chelators may be important regulators, although not to the extent of water quality growth inhibition. The actual importance of inimical chemical water quality in determining suitability of this habitat for A. tamarense remains unresolved. JF - ELSEVIER, AMSTERDAM (NETHERLANDS). 1993.

AN - 16668171; 3029302 AB - Measurements made in the outer ring of the northern polar vortex from October 1991 through March 1992 reveal an altitude-dependent change in ozone, with a decrease at the bottom of the vortex and a substantial increase at the highest altitudes accessible to measurement. The increase is the result of ozone-rich air entering the vortex, and the decrease reflects ozone loss accumulated after the descent of the air through high concentrations of reactive chlorine. The depleted air that is released out of the bottom of the vortex is sufficient to significantly reduce column ozone at mid-latitudes.

AN - 16665714; 3025003 AB - Several studies have addressed the likely effects of CO sub(2)-induced climate change over the coming decades, but the longer-term effects have received less attention. Yet these effects could be very significant, as persistent increases in global mean temperatures may ultimately influence the large-scale processes in the coupled ocean-atmosphere system that are thought to play a central part in determining global climate. The thermohaline circulation is one such process - Broecker has argued super(11) that it may have undergone abrupt changes in response to rising temperatures and ice-sheet melting at the end of the last glacial period. Here we use a coupled ocean-atmosphere climate model to study the evolution of the world's climate over the next few centuries, driven by doubling and quadrupling of the concentration of atmospheric CO sub(2). We find that the global mean surface air temperature increases by about 3.5 and 7 degree C, respectively, over 500 years, and that sea-level rise owing to thermal expansion alone is about 1 and 2 m respectively (ice-sheet melting could make these values much larger). The thermal and dynamical structure of the oceans changes markedly in the quadrupled-CO sub(2) climate - in particular, the ocean settles into a new stable state in which the thermohaline circulation has ceased entirely and the thermocline deepens substantially. These changes prevent the ventilation of the deep ocean and could have a profound impact on the carbon cycle and biogeochemistry of the coupled system.

Part I: Frontal-cyclone evolution and thermodynamic air-sea interaction AN - 16656596; 3660443 AB - The Experiment on Rapidly Intensifying Cyclones over the Atlantic was carried out over the western North Atlantic Ocean to provide temporally continuous comprehensive datasets from which to document the life cycle of extratropical marine cyclones. The most intense cyclogenetic event occurred on 4-5 January 1989 over the warm (>20 degree C) Gulf Stream current; the cyclone's central sea level pressure decreased by 60 mb in 24 h, from 996 to 936 mb. This study presents the synoptic-scale and mesoscale life cycle of this cyclone in two parts. Part I, presented here, describes the 24-h frontal-cyclone evolution through 6-h analyses of observations taken by specially deployed observing systems from air, land, and sea. The analyses of temperature, wind, and pressure about the incipient cyclone first illustrate the precursor signatures to cyclogenesis. The 850- and 500-mb temperature evolutions show a significant departure from the Norwegian frontal-cyclone model. In particular, the 850-mb analyses document 1) a storm-relative westward development of the warm front as a bent-back front into the polar airstream, and 2) the formation of a warm-core frontal seclusion in the post-cold-frontal cool air at the southwestern tip of the bent-back front. Analyses of sea level pressure provide a detailed account of cyclone intensification along the bent-back front. Infrared satellite imagery shows the evolution and immense size ( similar to 5000 km) of the cyclone's cloud signature, and a 250-km-scale comma-cloud system in the vicinity of the warm-core seclusion situated at the southwestern tip of the large-scale comma head. Thermodynamic air-sea interaction diagnostics reveal large upward fluxes of heat and moisture from the sea surface into the marine boundary layer of the evolving cyclone. The maximum of combined upward flux approached 3000 W m super(-2), several times larger than that typically observed in both extratropical and tropical cyclones. These fluxes exhibited extreme spatial variability, reflecting the mesoscale characteristics of the cyclone circulation.

The temporal and spatial variations of arctic aerosol physicochemical characteristics were studied relevant to the source, transport and transformation. Air trajectories arriving at the sampling sites generally provided useful information to interpret the aerosol chemistry. When the air masses passed over northern Russia, most of the aerosols were crustal dust, and approximately one-half of them were coated with sulfate. When the air masses were from northwestern Europe, solid particles, coated with sulfuric acid droplets and sulfate particles were the majority. These were probably formed by heterogeneous nucleation of H sub(2)SO sub(4) followed by partial or complete neutralization. Over open water, numerous large drops containing solid particles and cubic NaCl crystals were observed. However, over the frozen ocean, the drops and seasalt crystals were diminished. Instead, small sulfuric acid droplets, which were probably formed by homogeneous nucleation, were the principal aerosol species. At high altitudes (> 5 km), pure sulfuric acid droplets and sulfuric acid drops with foreign nuclei were the dominant aerosols; however, alumina particles occasionally appeared in large quantities. Sulfate aerosols were omnipresent in the arctic stratosphere, troposphere and planetary boundary layer, whereas few nitrate-containing particles were found and then only in the boundary layer.

AN - 16648510; 3001408 AB - Deepwater snappers are a valuable component of fisheries on slopes and banks in Hawaii and in much of the world's tropics. Line fishing simultaneously collected six of the seven lutjanid species that commonly occur in the major deepwater snapper fishery at Penguin Bank, Hawaii. The catch rate of each species showed diel variability; the patterns of some species were distinctly different. The depth distribution of feeding, differed considerably among species. Size of the predator species did not appear to be stratified by time of capture or median capture depth. Regurgitation of gut contents seemed to be reduced when fish were retrieved at a rate that was slower than used in commercial practice but rapid enough to prevent death or morbidity while hooked. The six snapper species ate considerable amount of a wide range of pelagic animals and demersal fishes and smaller quantities of a few invertebrate benthic groups. Etelis coruscans, Etelis carbunculus , and Aprion virescens formed a distinct, primarily piscivorous feeding guild. Pristipomoides filamentosus and Pristipomoides sieboldii formed a distinct guild dominated by zooplankton feeding. The few specimens of Pristipomoides zonatus appeared somewhat intermediate in diet. Important planktonic prey groups included crustaceans, pteropods, and large, pelagic, colonial urochordates (e.g., salps). Urochordates made a significant contribution to the diet even for some of the primarily piscivorous species. Major diel and seasonal shifts in diet were found only in P. filamentosus . Diet composition and depth and time of feeding (catch) suggests that considerable resource partitioning occurs among these deepwater snappers.

The mixing ratios of the three gases varied significantly both horizontally and vertically. Elevated concentrations were found in layers with high anthropogenic aerosol concentrations (Arctic Haze). The mixing ratios of CO sub(2), CH sub(4) and CO were highly correlated on all flights. A linear regression of CH sub(4) vs CO sub(2) for pooled data from all flights yielded a correlation coefficient (r super(2)) of 0.88 and a slope of 13.5 ppb CH sub(4)/ppm CO sub(2) (n = 186). For CO vs CO sub(2) a pooled linear regression gave r super(2) = 0.91 and a slope of 15.8 ppb CO/ppm CO sub(2) (n = 182). Carbon dioxide, CH sub(4) and CO also exhibited mean vertical gradients with slopes of 0.37, -4.4 and -4.2 ppb km super(-1), respectively. Since the carbon dioxide variations observed in the Arctic atmosphere during winter are due primarily to variations in the emissions and transport of anthropogenic CO sub(2) from Europe and Asia, the strong correlations that we have found suggest that a similar interpretation applies to CH sub(4) and CO. Using reliable estimates of CO sub(2) emissions for the source regions and the measured CH sub(4)/CO sub(2) and CO/CO sub(2) ratios, we estimate a regional European CH sub(4) source of 47 plus or minus 6 Tg CH sub(4) yr super(-1) that may be associated with fossil fuel combustion.

AN - 16632599; 3021023 AB - The discovery of the Antarctic ozone hole in 1985 led to international efforts to reduce emissions of ozone-destroying chlorofluorocarbons. These efforts culminated in the Montreal Protocol and its subsequent amendments, which called for the elimination of CFC production by 1996. Here we focus on CFC-11 (CCl sub(3)F) and CFC-12 (CCl sub(2)F sub(2)), which are used for refrigeration, air conditioning and the production of aerosols and foams, and which together make up about half of the total abundance of stratospheric organic chlorine. We report a significant recent decrease in the atmospheric growth rates of these two species, based on measurements spanning the past 15 years and latitudes ranging from 83 degree N to 90 degree S. This is consistent with CFC-producers' own estimates of reduced emissions. If the atmospheric growth rates of these two species continue to slow in line with predicted changes in industrial emissions, global atmospheric mixing ratios will reach a maximum before the turn of the century, and then begin do decline.

In this paper we use a simple model to estimate the total pre-fishery abundance of the cohort destined to return as 2SW maiden spawners for the 1975 to 1992 return years. The pre-fishery abundance estimator reconstructs the population by summing 2SW returns, and catches from fisheries on nonmaturing one sea-winter (lSW) salmon in Canada and Greenland, and 2SW salmon in Canada. A variety of methods were employed to estimate the total number of 2SW returns to North America. Uncertainties in underlying parameters are incorporated into the estimates to generate upper and lower bounds. Pre-fishery abundance has declined from a average of 745 thousand fish in the mid 1970s to an average of about 312 thousand fish from 1988-91. Average exploitation on the extant stock by 1SW fisheries of about 35% showed no trend over the entire period. Exploitation by the 2SW fisheries of Newfoundland-Labrador declined from an average of 48% from 1974-83 to 32% since 1984. Exploitation by the 1992 2SW fishery on the 1991 cohort was about 15%. Reductions in 2SW exploitation have resulted in an increasing fraction of the cohort returning as 2SW salmon but the reductions have not been sufficient to offset a general decline in pre-abundance. Without the reductions in the interceptory fisheries of Greenland and Newfoundland-Labrador, total 2SW returns would have been reduced by 60 to 70,000 salmon in recent years.

Part 2: Mesoscale structure and diagnostics AN - 16627467; 3660444 AB - This is the second of two articles describing the evolving structure and selected physical processes within an intense extratropical marine cyclone observed during the Experiment on Rapidly Intensifying Cyclones over the Atlantic (ERICA) field program. Part I describes the 24-h frontal-cyclone evolution through 6-h horizontal analyses of observations taken by specially deployed observing systems from air, land, and sea. Part II presents frontal-scale and precipitation structures and physical processes from analyses based primarily on research aircraft observations taken during three phases of the cyclone's life cycle. Horizontal analyses at 350 m above ground level describe the cyclone's mesoscale frontal baroclinic structure and associated flow patterns. The vertical structure and evolution of the cyclone's cold front, warm front, and bent-back front are illustrated in cross-sectional analyses of potential temperature, wind velocity, potential vorticity (PV), front-relative transverse flow vectors, diabatic heating, and PV tendencies. Of particular interest are the lower-tropospheric positive PV anomalies within the warm front and within its bent-back extension westward into the polar airstream. Airborne radar reflectivities and Doppler velocities provide a detailed account of the precipitation elements and associated wind flow patterns in the vicinity of the fronts, including mesoconvective radar reflectivities of greater than 50 dBZ and cross-frontal convergent flow exceeding -20 x 10 super(-4)/s. Time series traces of the 1-s aircraft observations show large and rapid changes in meteorological variables as the aircraft crossed the narrow frontal zones.

Eight high-volume aerosol filter samples were collected in tropospheric air over the pack ice. In these sampling periods, continuous O sub(3) measurements were made and trace gases were collected in flasks. For all samples, total elemental bromine collected on the filters in excess of the estimated sea salt component (XSFBr) was found to anticorrelate strongly (r = -0.90) with the mean ozone concentration observed during the sampling period. These findings are similar to earlier observations at Alert and Barrow. Air samples collected during these periods were analysed for Br-containing gases and hydrocarbons. None of these compounds were well correlated with either O sub(3) or XSFBr concentration over the course of the experiment. This is probably because variable conditions of local meteorology, atmospheric structure and geographic location influenced the degree to which O sub(3) was depleted, by affecting the size of the reaction reservoir and the source(s) of the reactants. Samples collected in the surface ( similar to 50 m deep) isothermal or slightly stable layer (SSL) over pack ice and with light winds from the direction of the central Arctic showed the highest O sub(3) depletions. When winds were from the direction of open water, significantly higher O sub(3) and lower XSFBr values were observed. When the SSL was not present, samples collected below the strong inversion showed less O sub(3) destruction and lower XSFBr concentrations than similar low altitude samples collected within the SSL. This is consistent with the notion of a larger reservoir volume available for reaction. Gas and aerosol chemistry results were compared for two samples collected close spatially and temporally over ice north of Spitsbergen. Our data indicate that (1) CHBr sub(3) may be the key organobromine species supplying Br atoms and BrO radicals in a heterogeneous photochemical reaction cycle causing the photolytic destruction of O sub(3) in the springtime. Arctic surface layers, and (2) ambient hydrocarbons (especially C sub(2)H sub(2)) are depleted during O sub(3) destruction, and may be important in the overall reaction mechanism. This catalytic O sub(3) depletion process was observed to occur to an extent causing near-total O sub(3) destruction in the SSL over a 1-2 d period. Thus, relatively rapid photochemical reactions between atmospheric Br, hydrocarbons and aerosols are suggested as driving the photolytic O sub(3) destruction process.

AN - 16625367; 3003571 AB - The coupled ocean-atmosphere-land climate system is characterized by substantial amounts of variability on a wide range of spatial and temporal scales. This natural variability of climate increases the difficulty of detecting climate change attributable to increasing greenhouse gas concentrations. A key issue in climate research is obtaining a better description of this variability and the physical mechanisms responsible for it. One of the important physical processes contributing to this variability is the interaction between the land surface and the atmosphere. Through its effect on the surface energy flux components, the land surface can exert a pronounced effect on the variability of the atmosphere. The potential importance of such interactions for climate variability is examined through the use of numerical modeling studies. The physical mechanisms governing the time scales of soil moisture variability in the model are outlined, and observational evidence is presented supporting this analysis.

During June through August 1990, and in May 1991, we observed and photographed male and female flowers of H. wrightii collected between Cape Lookhout and Oregon Inlet, North Carolina. Although we did not find seeds of H. wrightii in the sediment of that region, seeds were found south of Cape Lookhout in Bogue Sound in 1991. Our observations confirm that Dare County, North Carolina, is the northern limit for occurrence of H. wrightii along the Atlantic coast of North America.

AN - 16619847; 3038595 AB - The while sturgeon (Acipenser transmontanus ) supports important recreational and commercial fisheries in the lower Columbia River. Little is known about the ecology of white sturgeon, and the feeding ecology in particular has received only limited investigation. From April through October 1988, the feeding ecology of juvenile white sturgeon was studied in two areas of the lower Columbia River. Overall, the tube-dwelling amphipod Corophium salmonis was the most important prey for the two size classes of juvenile white sturgeon studied. However, during all sampling periods and at both areas (River Kilometers (RKm) 153 and 211), Size Class I white sturgeon (144-350 mm fork length) preyed more heavily on C. salmonis than did Size Class II white sturgeon (351 to 724 mm). Index of Feeding analysis indicated that juvenile white sturgeon in both areas contained less food in September-October than in either May-June or July-August. Generally, the relationships between densities (abundances) of specific benthic organisms and white sturgeon diets were poor at RKm 153 and 211. Despite the importance of Corophium salmonis in the diets of juvenile white sturgeon, it was not abundant in the benthos (mean density, < 185 organisms/m super(2) in April and September).

AN - 16616408; 2984379 AB - The authors analyzed experimental gill-net catches of spotted seatrout Cynoscion nebulosus at 28 stations in various estuarine habitats over 3 years (1988-1990). Cluster analysis indicated that the 28 stations reduced to three "natural" groupings representing salinity zones that correspond to upper (oligohaline, 0-9ppt), intermediate (mesohaline, 10-14ppt), and lower (polyhaline, 15-30ppt) estuarine zones. Principal components analysis applied to log-transformed gill-net catches yielded a two-factor model that explained 78% of the variation in the data; factors were interpreted as recruit size (females smaller than 31 cm in total length and males smaller than 26 cm) and spawner size (females larger than 31 cm and males larger than 26 cm). Both recruit and spawner models were highly significant (P < 0.0001), and the zone-by-season interaction accounted for the greatest proportion of the variation in the models (P < 0.0001). Abundances of recruit and spawner spotted seatrout were greatest in the lower estuarine zone (15-30ppt) during the spawning season (May-August), when both recruit and spawner abundances had high positive correlations with salinity (P < 0.01). After the spawning season (September-December), spawners were uniformly distributed over all estuarine zones whereas recruits were significantly more abundant (P < 0.01) in the upper estuarine zone (0-9ppt). During this time, recruit spotted seatrout abundance showed a high negative correlation with salinity (P < 0.01).

AN - 16615893; 3035648 AB - Changes in buoyancy in fertilized bathypelagic eggs of the walleye pollock, Theragra chalcogramma , collected from Shelikof Strait in the Gulf of Alaska were measured under controlled laboratory conditions in density gradient columns from 90 h post-fertilization through hatching. Eggs were incubated at 6 degree C and exposed to either diel light or constant dark. Eggs held under diel light conditions became more dense than eggs under constant dark beginning < 10 h after exposure to light and remained so until 12 h before hatching. Eggs held under constant dark then became more dense than those under diel light. Hatching of eggs under both conditions began at the same time but eggs under diel light showed a delayed hatching rate. Light-induced changes in egg density indicate the ability of walleye pollock eggs to respond to external stimuli and thereby alter their position in the water column in an ecologically meaningful way.

Effects of the molt cycle on blue crab metal metabolism and metallothionein. AN - 16614296; 3043758 AB - The discontinuous-growth process (i.e. the molt cycle) of crustaceans and their ability to accumulate and regulate metals provide a unique system to study how alterations of specific metabolic processes can affect metal metabolism. We have shown that the extensive physiological and biochemical changes that take place during the molt cycle, particularly after ecdysis, affect metal metabolism in the blue crab, Callinectes sapidus . For example, there are significant changes in the concentrations of copper and zinc in both the hemolymph and the digestive gland. Some of these occur quite rapidly. It has been possible to demonstrate shifts in the cytosolic distribution of copper and zinc in the digestive gland within 90 min of ecdysis that are correlated positively with the degadation of hemocyanin and the liberation of copper. A descriptive model has been developed that describes fluxes of copper and zinc during the molting process. JF - Marine environmental research. 1993.

The results showed that more comprehensive current measurements were needed to interpret the wastewater dilution measurements, and SEFLOE II was scheduled to include the additional data collection. Continuous series of current measurements were obtained at four outfalls both to support other measurements being collected during intensive survey periods and to compile long-term statistics of the different characters of ocean currents at the outfalls. Current meters were installed at two depths on each mooring.

The host crab died subsequent to hatching of the fish eggs in one incident, but not in another. Because of gill damage caused by the egg mass, the fish-crab relationship is properly termed parasitism rather than commensalism. Two of 14 ovigerous females were parasitized, while no infected males were found in 824 examined, although evidence of parasitism of male crabs was found.

AN - 16603821; 3033262 AB - Faeces of the green turtle, Chelonia mydas , washed ashore in large numbers at a beach park in Hawaii over a 40-day period in 1989. The formed pellets were originally misidentified as being from pigs or humans, and therefore were perceived as a pollutant of potential health hazard to humans. However, bacteriological analysis of the nearshore waters indicated low and legally acceptable levels of faecal coliforms and enterococci. Similar diminished levels were also found in direct cultures of the fresh pellets. Green turtle faeces have been known to drift ashore in Hawaii, but never in the quantities recorded during this short-term event. The reason for the occurrence could not be determined, but several possible explanations are given.

The continental run reconstruction model is based on the simple premise that the range of feasible exploitation rates and population parameters must be internally consistent with observed catches and returns to rivers. A system of constraint equations was developed to simultaneously bound exploitation estimates in each fishery and the relative fraction of the population present in the fishery. The nonlinear equations for the model parameters were examined graphically to define a feasible set of population parameters. The key parameters of interest are the fishery area exploitation rate for Greenland and the fraction of the population returning from Greenland. This paper introduces new data on the estimation of grilse returns in Newfoundland, catches of maturing one sea-winter (1SW) salmon, and utilizes several key parameters including the mixture of sea-age composition by market category, and estimates of the nonmaturing 1SW component of the Newfoundland Labrador catch. We also introduce the concept that some fraction of the population is likely to be unavailable to any fishery. JF - ICES, COPENHAGEN (DENMARK). 1993.

AN - 16600990; 3043821 AB - A suite of chemical and biochemical parameters was measured in three species of benthic flatfish (English sole, Parophrys vetulus ; rock sole, Lepidopsetta bilineata ; and starry flounder, Platichthys stellatus ) sampled from up to five sites in Puget Sound, WA, USA, to assess the sensitivity of the parameters to differences in levels of contaminant exposure and the relative merit of the use of a suite of indices for assessing exposure and sublethal effects. The indices examined were hepatic levels of polychlorinated biphenyls (PCBs) and biliary fluorescent aromatic-compound concentrations, hepatic activities of aryl hydrocarbon hydroxylase and ethoxyresorufin-O-deethylase, and levels of total hepatic GSH and hydrophobic DNA-xenobiotic adducts; the last-mentioned were determined by using the super(32)P-postlabeling assay. The results showed that the indices examined could discriminate among sites exhibiting different degrees of chemical contamination; however, species differences in the range of response of some indices were observed. Additionally, the use of multiple indices appeared to enhance the assessment of contaminant exposure and sublethal effects. JF - Marine environmental research. 1993.

AN - 16600880; 3043747 AB - During May 1990, satellite-tracked buoy, water property, and ichthyoplankton observations were collected over the Shelikof sea valley in the western Gulf of Alaska. These observations revealed the presence of an anticyclonic mesoscale eddy (radius 10-12 km). Characteristics of the eddy included a relatively warm, low-salinity core and high concentrations of walleye pollock larvae. The eddy remained nearly stationary for several weeks before moving westward into shoaler waters. During translation, the eddy maintained its characteristics. Speeds from geopotential topography and direct measurements agreed. Current speeds generally increased with distance from the center of the eddy; maximum speeds (> 30 cm/s) existed near the perimeter. Analysis of water properties indicates little or no exchange of mass occurred with adjacent waters. The lack of dispersion permits us to estimate larval mortality ( less than or equal to 4.7%/d) based only on biological factors.

AN - 16597183; 2989805 AB - The effect of research programs designed to increase precision in estimates of stock assessment parameters were evaluated for Gulf of Mexico king mackerel Scomberomorus cavalla . Monte Carlo simulations of the entire assessment analysis were used, consisting of separable virtual population analysis (VPA), calibrated VPA, estimation of target fishing mortality rate, and projection of catch at that rate. The distribution of estimates of allowable biological catch (ABC) from the simulations indicated that realistic improvements in research could substantially reduce the uncertainty in ABC estimates from a 40% to a 20% coefficient of variation. Expected yield for risk-averse strategies increased with enhanced research programs. Opportunity losses of forgone yield and lost surplus were diminished as well. Benefits of research combined with risk-averse management strategies to the fishery and to the economy appear to substantially exceed the costs of the research.

AN - 16596547; 2996848 AB - Historical time series of riverine water discharge, nitrate concentration and nitrate flux were analyzed. Water discharge variability is greatest in association with the annual cycle. Relatively little variation in water discharge occurs at time scales greater than one year. In contrast, nitrate concentration exhibits strongest variability at decadal time scales. This variability is more cyclic than trend-like. The annual water discharge and nitrate concentration cycles are similarly phased, but only weakly coherent. Nitrate flux variations exhibit a low amplitude, long-term modulation of a dominant annual cycle. Predictor-hindcastor analyses indicate that truly skilled forecasts of all three fields are feasible. Oceanographic field data are used to evaluate impacts. JF - ASLO/SWS, (USA). vp. 1993.

AN - 16595719; 2989714 AB - Population recovery-related management actions have been taken to rebuild the endangered Hawaiian monk seal (Monachus schauinslandi Matschie) colony at Kure Atoll in the Northwestern Hawaiian Islands since 1981. In 1990, composition of the Kure population was determined by a combination of methods to identify all seals using the atoll. The resident 1990 population included 75 seals, and an increasing trend in the mean annual beach count of seals over the last decade is apparent. Two major changes have occurred in the population since 1985. A shift in the adult sex ratio (males/females), from 2.7:1 to 0.8:1, has developed and appears to be due to both adult male losses and increased recruitment of females. Also, the declining trend in births apparent between 1981 and 1986 has been reversed. These findings suggest cause for optimism for the continued growth of this population.

AN - 16590805; 3034159 AB - This paper documents the meteorology and flow climatology of Amsterdam Island, a World Meteorological Organization baseline observatory located in the southern Indian Ocean. The island is strongly influenced by two meteorological systems: the subtropical anticyclone and the westerlies, known as the roaring forties. Westerly surface winds dominate ground-level flow on the island, which receives an annual average precipitation of 1100 mm. A 10-year back air trajectory climatology at 850 hPa to the island showed the same predominant westerly-southwesterly flow (55% of the period). Special emphasis was placed on trajectories that had their origin on the African continent because this was the predominant nonmarine source of trace materials that could be transported to Amsterdam Island. This transport, most frequent in the winter and early spring, coincided with the winter peak of continental radon. A comparison of trajectories and 12-h precipitation amounts on the island showed that most of the rain coincided with southwesterly flow, but many large individual events were frequently associated with northerly and westerly flow regimes. Meteorological information about local conditions and flow climatology is necessary to aid in the interpretation of atmospheric chemistry measurements made at global stations such as Amsterdam Island.

AN - 16588529; 2983439 AB - This paper reviews and discusses the uses of genetic markers in analyzing the composition of population mixtures of fishes. Such analyses require (1) the existence of genetic differences identified in baseline data from contributing populations, and (2) an adequate sampling of individuals from the mixture to characterize its composition. Genetic analyses of complex population mixtures of salmonids began around 1980 and subsequently have been increasing; applications have included estimates of geographic origins in marine and freshwater fisheries, and of ancestral origins in populations reestablished from multiple sources. The potential for applications of genetic analyses of population mixtures is more limited in most marine species because such species are typically less genetically subdivided than salmonid species. However, genetic analyses are feasible in any species in areas of intermingling of genetically distinguishable populations. In addition, genetic marking by preferential breeding of genetically distinguishable individuals may be used to establish genetically distinct cultured populations within species amenable to artificial propagation.

AN - 16587965; 3017628 AB - Ovigerous female red king crab, Paralithodes camtschaticus monitored with ultrasonic biotelemetry, displayed distinct seasonal shifts in habitat use and bathymetric distribution. Crab occupied deep water between June and mid-November, relatively shallow water between mid-November and early March, and returned to deeper water prior to molting and mating in spring. Females were nonrandomly distributed within both depth ranges but seasonally changed their behavior and degree of association with conspecifics. Tagged crab were more aggregated (lower mean nearest neighbor distances) in winter than in summer and fall. Winter SCUBA observations supported these results; females of mixed age-classes formed dense aggregations in shallow water, and crab exhibited "podding" behavior similar to that reported for younger age-classes. Adult males were associated with aggregations during late winter and early spring. Observations from the manned submersible Delta indicated that females were nonrandomly distributed in the deepwater habitat as well and probably formed loosely knit feeding aggregations there. Seasonal changes in aggregation densities and benthic areas used were the same during the two consecutive years of this study.

Vacuum packaging suppressed growth of L. monocytogenes by 10- to 100-fold in samples with 3 or 5% NaCl. Inhibition related to NaCl concentration was most apparent at 5 degree C and L. monocytogenes populations were held below 10 super(2) CFU/g by 6% NaCl. Growth of a 327 CFU/g inoculum was about 10-fold greater than a 10 CFU/g inoculum at 10 degree C and 100-fold greater at 5 degree C.

AN - 16576404; 3013062 AB - With the passage of the Magnuson Fishery Conservation and Management Act of 1976, the United States extended its jurisdiction over fishery resources from 12 to 200 miles offshore. The act's purpose was to end overfishing attributed to European and Asian fisheries within the U.S. Exclusive Economic Zone (EEZ) and to encourage U.S. fishery development. Ironically however, the United States traded overfishing by once-dominant foreign fleets for domestic overcapitalization throughout the country and overfishing in some regions. Congress is now considdering reauthorization of the Magnuson Act, and it is timely for us to reconsider the basic fundamentals of fisheries management in order to rebuild its depleted stocks--with an aim toward sustainable catches over the long term. One manifestation of our fishery problems is conflicts between user groups, which creates politically difficult allocation decisions that are often limited by the non-selective nature of specific fishing gear. As demand for more species increases, scientific information necessary to assess the status of the stocks and the effects of their utilization becomes critical for sound management. This information is often lacking and this uncertainty compounds the difficulty of developimg and implementing management actions.

AN - 16574980; 2992843 AB - We used a three wavelength nephelometer (449, 536 and 690 nm) and an aethalometer on board the NOAA King Air research aircraft to assess the contributions of aerosol optical scattering and absorption to shortwave extinction. The measurements were made over south-central New Mexico in February and July 1989. The winter measurements revealed a shallow, polluted planetary boundary layer with cleaner air above. The summer measurements showed a uniformly mixed planetary boundary layer extending from ground level to the operational ceiling of 4.5 km above ground. In both cases the total optical thickness values for the column were similar (0.03) and the fractional contribution of aerosol absorption to the extinction was between 5 and 10%. These results suggest that the aerosol extinction in summer and winter is similar, even though the planetary boundary layer thickness is quite different during the two seasons.

AN - 16571675; 3001601 AB - Injuries observed on endangered Hawaiian monk seals (Monachus schauinslandi ) at Laysan Island and French Frigate Shoals in the northwestern Hawaiian Islands in 1988 and 1989 were classified into six major types, based on the source of the wounds: mating attempts by adult male monk seals; nonmating aggressive interactions with other seals; attacks by large sharks; attacks by cookiecutter sharks (Isistius brasiliensis ); contact with coral reef or debris; and entanglement in netting or marine debris. At both locations, injuries inflicted by adult male seals during mobbing incidents, in which many males attempt to mate with one seal, were seen more frequently than other types of injuries in 1988 and 1989. Injury data from 1982-1987 at Laysan Island and from 1985-1989 at French Frigate Shoals were used to compare the distribution of mating injuries inflicted by adult males and injuries inflicted by large sharks over size and sex classes of seals.

AN - 16567970; 2980519 AB - Zooplankton biovolume data from a multi-frequency Acoustic Profiling System were used to construct biovolume-size spectra for the Gulf Stream and the Southern California Bight. These spectra were linear through most, but not all, of the size range sampled (0.025-4.00 mm, ESR). Analysis of covariance was sometimes a useful tool to distinguish among spectra taken at different times and places. Difference spectra offered an alternative method of visualizing disparities between spectra. We compared our acoustically-derived spectra from the Gulf Stream with those obtained from other oceans with different samplers and those obtained in the same waters with a different sampler. The results indicate that differences attributable to sampler bias within the same system presently make it difficult, if not impossible, to interpret comparisons from different samplers in different ecosystems.

AN - 16514301; 2958977 AB - The annual springtime depletion of Antarctic ozone has been shown to be due to the action of chlorine species, activated by reactions occurring on the surfaces of polar stratospheric clouds (PSCs). Similar reactions may also take place on the surfaces of liquid sulphuric acid aerosols when the temperature is too high to permit the formation of PSCs. Such processes may have been facilitated following the eruption of Mount Pinatubo in June 1991, when unprecedented amounts of sulphur compounds were injected into the stratosphere. We present observations of Antarctic chlorine dioxide abundances in the austral autumn and winter of 1991 (when aerosol concentrations were at background levels) and 1992 (greatly enhanced aerosol concentrations).

AN - 16512335; 2958914 AB - In situ measurements of stratospheric sulphate aerosol, reactive nitrogen and chlorine concentrations at middle latitudes confirm the importance of aerosol surface reactions that convert active nitrogen to a less active, reservoir form. This makes mid-latitude stratospheric ozone less vulnerable to active nitrogen and more vulnerable to chlorine species. The effect of aerosol reactions on active nitrogen depends on gas phase reaction rates, so that increases in aerosol concentration following volcanic eruptions will have only a limited effect on ozone depletion at these latitudes.

AN - 16511397; 2952875 AB - Inferred dry deposition rates of SO sub(2) determined using concentrations from a continuously operated chemical monitor are compared to results obtained from weekly averages, a protocol that is currently employed in many dry deposition networks. Results from two years of data were compared to evaluate any seasonal differences in the uncertainty using a weekly sampling protocol. In general, a weekly sampling protocol was found to underestimate the flux by 40% during the growing season when the diurnal cycle of estimated deposition velocity was found to correlate with measured hourly concentrations. For leafless forest conditions, no consistent correlation was found. This results in a 20% underestimate of the flux on an annual basis.

Brock and McClain's (1992) 4-year time series of pigments over the Arabian Sea appears to reveal a slowdown in production over much of this basin. Apparently, the entire southwest monsoon relaxed beneath the tremendous pall of the El Chichon aerosol cloud that had overshadowed the region 4 months earlier, producing dramatically reduced concentrations of phytoplankton during summer and fall 1982.

AN - 16495570; 2942203 AB - A serious underprediction of ambient sulfate (SO super(2) sub(4) super(-)) by two comprehensive, Eulerian models of acid deposition, the Regional Acid Deposition Model (RADM) and the Acid Deposition and Oxidant Model (ADOM), was found in the National Acid Precipitation Assessment Program phase of the Eulerian Model Evaluation Field Study (EMEFS) model evaluation. Two hypotheses were proposed to explain the cause of the underprediction in RADM: insufficient SO super(2) sub(4) super(-) production by nonprecipitating convective clouds and insufficient primary SO super(2) sub(4) super(-) emissions. Modifications of the RADM cloud and scavenging module to simulate nonprecipitating cumulus clouds better are described in detail. Three contrasting pairs of tests using data from the EMEFS were applied to these hypotheses: source vs downwind regions, mid-summer vs late summer seasons and sunny-dry vs cloudy-wet synoptic types.

AN - 16494472; 2942236 AB - The Regional Acid Deposition Model (RADM) has been applied to several of the field experiments that were part of the Acid Model Operational and Diagnostic Evaluation Study (AcidMODES) to assess the model's ability to simulate photochemical production of ozone in regions dominated by point source emissions. The comparison of model simulations at different grid resolutions suggests that increased resolution improves the simulation of ozone photochemistry in such regions. Further analysis of NO sub(x) and HO sub(x) concentrations and photochemical production rates of ozone, however, show that the model's response to large point source emissions is very unsystematic both spatially and temporally. This is due to the model's inability to simulate realistically the small-scale (subgrid) gradients in precursor concentrations in and around large point source plumes. Because of the inherently nonlinear nature of ozone photochemistry with respect to concentrations of NO sub(x) and VOC, ozone formation rates in model grid cells depend enormously on grid resolution, dispersion rates (primarily wind speed and mixed layer height), chemical background (VOCs and radicals) and NO sub(x) emission rates.

World Meteorological Organization Background Air Pollution Monitoring Program (WMO BAPMoN). Field and laboratory procedures are discussed, siting criteria are examined, station histories are documented, and four Soviet quality assurance techniques are discussed. Comparison of data from three Soviet BAPMoN stations with data from three U.S. BAPMoN stations indicate that sulfate concentrations are comparable but that U.S. samples are typically much more acidic. Soviet samples tend to have higher concentrations of cations of soil origin and higher concentrations of ammonium.

AN - 16468281; 2920252 AB - Studies were performed to determine effects of environment and physiology on the formation of daily increments in water flounder otoliths. Otoliths from embryonic to 1-yr-old laboratory-raised winter flounder Pleuronectes americanus and young-of-year wild-caught specimens were examined, and growth patterns were determined from photographs taken on light and scanning electron microscopes. Behavioral observations were made from hatching through metamorphosis. Daily growth increments of otoliths from larval winter flounder were enumerated, and a growth curve was derived describing the first 2 months of life. Growth was best described by a Gompertz-type curve. The relationship between sagitta size and fish length was exponential for larvae, but linear during the remainder of the first year. Sagittae were compared with fish length for both wild and laboratory-reared juveniles and exhibited the same relationship for each. The change in relationship between sagitta size and fish length coincided with changes in dimensional growth of the fish.

AN - 16466342; 2920197 AB - A manned submersible was used in the eastern Gulf of Alaska to observe spatial distributions of Pacific ocean perch Sebastes alutus and other Sebastes spp., and count rockfish for comparison with bottom-trawl catch rates. Twenty submersible dives were completed in 1988 and 1989 at depths of 188-290 m. Approximately 80% of the 5317 rockfish observed from the submersible were Pacific ocean perch. Most adult Pacific ocean perch were in groups of 2-200 over flat, pebble substrate. Fish within a group were 1-4 m apart, usually oriented into the current, and 0-7 m above bottom. Most juvenile Pacific ocean perch, and juveniles and adults of other Sebastes spp., were associated with rugged habitat (cobble, boulders, pinnacles, and coral). Densities of Pacific ocean perch estimated from bottom-trawl catches were approximately twice those observed from the submersible, indicating that the bridles and other doors herded fish into the trawl. Bottom-trawl surveys may overestimate Pacific ocean perch abundance because of this possible herding effect and the preference of adult Pacific ocean perch for smooth (trawlable) substrate.

Comparisons were made between nets equipped with Turtle Excluder Devices (TEDs) and standard shrimp nets. Three types of TEDs were tested: Georgia TEDs with and without accelerator funnels, and Super Shooter TEDs with funnels. Fishing areas, time of day, and duration of tows were controlled by the captain of each vessel to simulate commercial conditions. A statistically-significant (P < 0.05) mean loss in shrimp catch-per-unit-effort (CPUE) of 0.24 lb/h (3.6%) and 0.93 lb/h (13.6%) was exhibited by nets equipped with Georgia TEDs (with and without funnels, respectively) compared with standard nets. There was no significant difference in shrimp CPUE between standard nets and nets equipped with Super Shooter TEDs with a funnel.

AN - 16459218; 2920788 AB - Size-specific fecundities of spiny lobster Panulirus marginatus were compared for two time-periods: pre- and early exploitation or "before" (1978-81), and post-exploitation or "after" (1991). Fecundity was further evaluated within each time-period at two collection sites that represented the major lobster fishing grounds (Maro Reef and Necker Island) in the Northwestern Hawaiian Islands. Complementary data on egg size and spawning-frequency index were compared between study sites and time-periods. Study sites and time-periods had no observable effects on egg size or spawning frequency, and there was no temporal effect on fecundity at Maro Reef. Fecundities at the two sites differed, however, "after" size-specific fecundity was an estimated 16 plus or minus 9% greater than "before" fecundity at Necker Island. Observations suggest that the recent increase in fecundity at Necker Island may reflect a compensatory (density-dependent) response to greater exploitation at this site. Results are discussed in terms of evidence for density-dependent responses in other, exploited spiny lobster stocks.

AN - 16452517; 2920526 AB - The spatial distributions of marine biota are frequently patchy. Samples taken from these populations are characterized by values which are mostly small, relative to the population mean, and a few that are very large. It is therefore difficult to estimate stock size using conventional methods. We performed Monte Carlo simulations based on trawl data for Dungeness crab Cancer magister and compared the behavior of three estimators of central tendency: sample mean, geometric mean, and a lognormal estimate. Although the sample mean is unbiased, results indicate that single estimates of the population mean (and thua population estimates obtained using area-swept) may be overly sensitive to extreme values; confidence intervals are large and capture the true value at a level well below that prescribed. Estimates of the geometric mean exhibit more stable behavior about its parameter, with mixed results for the lognormal estimate. We propose a conservative approach based on comparison of trends found in each of the three estimators. Moreover, we suggest that abundance of aggregated stocks should be indexed with an estimator that has more desirable statistical properties, such as the geometric mean. This may reduce error associated with conventional fisheries stock-assessment practices and thus provide for more effective management of overdispersed stocks.

Of all juvenile and adult stomachs, 49% contained prey, primarily fish (teleosts and skates). Of stomachs from pups, 80% held food remains consisting almost exclusively of soft blue crabs. The mean percentage of stomach content volume to BW is 1.16 for pups, and 0.42 for juveniles and adults. Daily ration estimates as percentage of mean BW are 1.43 for pups, and 0.86 for juveniles and adults. Annual food consumption is estimated to be 5.1 times the mean BW for pups, and 3.1 times for juveniles and adults.

We suggest that these measures are indicators of stress associated with environmental conditions. Because croaker from different positions along the pollution gradient were distinguishable, it appears that they remain for extended periods within areas of degraded environmental quality.

AN - 16424828; 2903343 AB - Immunological detection of yolk protein was used to assess predation by pelagic amphipods (gammarid and hyperiid), mysids, and euphausiids on eggs and yolk-sac larvae of walleye pollock Theragra chalcogramma during 1988 and 1989. Consumption estimates were made on the basis of frequency of positive immunoassays, assay detection times (gut clearance time), predator abundance, and spatial overlap of predators and prey. From our results gammarid amphipods and euphausiids were important predators on eggs and yolk-sac larvae, respectively. Gammarid amphipods alone consumed about 14% of the standing stock of pollock eggs in 1989. These results were compared with those from clearance rate experiments of predators feeding on pollock eggs in 300-1 bags. In general, clearance rate estimates of egg consumption were lower than those determined from gut contents.

The results showed that more comprehensive current measurements were needed to interpret the wastewater dilution measurements, and SEFLOE II was scheduled to include the additional data collection. Continuous series of current measurements were obtained at four outfalls both to support other measurements being collected during intensive survey periods and to compile long-term statistics of the different characters of ocean currents at the outfalls. Current meters were installed at two depths on each mooring.

Volume 1. Technical memo. AN - 15688951; 3964254 AB - The Exxon Valdez ran aground on Bligh Reef, Prince William Sound, Alaska on March 24, 1989, spilling millions of gallons of Prudhoe Bay crude oil (PBCO). During the weeks following the spill, large amounts of oil flowed towards southwestern Prince William Sound, and as a result, many shorelines were oiled. In the study, edible flesh of fish, marine mammals, and shellfish from 22 native subsistence food collection areas and from two reference areas (Angoon and Yakutat) were analyzed for aromatic compounds (ACs). Vertebrates can readily biotransform ACs to metabolites that are concentrated in bile for excretion. This process greatly limits the accumulation of ACs in tissues such as edible flesh. Thus, for fish and marine mammals, bile was first analyzed for the presence of fluorescent aromatic compounds (FACs) as an indication of exposure to petroleum.

The observed relation between metal concentration and fish length was unexpected for biologically essential elements such as copper, iron, manganese, selenium and zinc. The problem of bias in estimating mean concentrations when such relationships exist is discussed with reference to copper. Possible ways of reducing bias and variance when analysing monitoring data to detect spatial and temporal trends are considered.

Sediments were analysed for total aluminium, silver, arsenic, cadmium, chromium, copper, iron, mercury, manganese, nickel, lead, selenium, silicon, tin, thallium and zinc and the data used to develop a geochemical model for characterizing variability observed in trace metal concentrations in natural sediments. Metal concentrations predicted by the models were compared with those occurring in uncontaminated geological materials which showed that baseline relationships were valid for the entire region sampled. The linear regression of metals on aluminium used to model the metal content in baseline sediments is useful for resolving concentration differences due to differences in mineralogical/textural composition and/or small to moderate contaminant enrichments. The model provides a statistical basis for reducing variability and bias in measured concentrations, for increasing comparability of metal concentrations in sediments across large regional and intercoastal areas and for improving the differentiation of natural and contaminated sediments on the basis of total metal concentrations. Examples of the application of baseline models to pollution studies are given. There are 41 references.

After 5 d, the initial direction of movement of the oil was abruptly reversed, and then changed again a few days later. A simple empirical hindcasting model, including a large-scale flow component, wind drift, and tidal currents, was used to identify the oceanic processes responsible for the changes in direction of the oil. Wind drift was the single most important factor in determining the overall displacement of the oil, but it could not fully account for the sudden reversal in direction. This reversal was surge-like and coincided with an increase in sea level along the central California coast. From changes in sea-surface temperature, it was suggested that the reversal was related to the onset of the Davidson Current, or other large-scale flow phenomena. There are 43 references.

In 1988, legislation was enacted, making dumping illegal after the end of 1991. Studies are being carried out to assess the effects of dumping on marine organisms, and the distribution of spores of Clostridium perfringens has been monitored to define the area affected by the sludge. The area covered by the dumpsite and the distribution contours of C. perfringens spores in surface sediments are shown on a map. The results suggested that the dumped sludge did not move onto the continental shelf where most commercial marine resources are obtained. Data on other contaminants are being analysed and will be compared with the Clostridium data.

GLERL methods were based on component supply estimates that could not predict evaporation errors but were more accurate than water-balance residual estimates, and forecasts of residual supplies could not utilize future improvements in models, data collection and climate outlooks. Comparison of GLERL results with those of other-agency forecast techniques that were derived statistically from residual supplies indicated that errors should be identified where there were large differences between methods. The performance of GLERL-recommended methods was superior to that of other agencies for forecasting either component or residual supplies and the largest source or error in GLERL NBS forecasts was precipitation error.

Cyclic changes of positive and negative divergence were evident but there was little net change in area for several days, and mean divergence was only minus 0.000002 per second. Divergence often occurred during flood tidal currents, and the observed changes could be linked to the rise and fall of the pycnocline driven by an internal semi-daily tide. The results suggested that horizontal velocity divergence could be ignored in the development of a concentration model for pollock larvae.

The advantages and disadvantages of this approach to marine oil spills are indicated.

Significantly greater numbers of pathological conditions were found in fish from polluted urban embayments such as Boston harbour, Mass., and Raritan bay. Statistical analyses indicated that polycyclic aromatic hydrocarbons, DDT, and chlordanes in sediments, stomach contents, liver, or bile of the fish were significant risk factors for development of certain types of lesion, but concentrations of polychlorinated biphenyls in sediments and tissues were not significant risk factors for any of the lesions observed. The risk of hepatic disease increased with the age of the fish, and lesions were more common in fish collected in spring than in winter when spawning migration was taking place.

The potential effects of varying contaminant concentrations on AEs were also investigated. The direct measurement method uses total organic carbon as a tracer and gave AE values between 45.9-60.4 per cent while the dual-labelled method uses 51 chromium as a non-assimilated tracer and yielded AE values above 100 per cent indicating a failure of this approach. Selective feeding by Diporeia resulted in a failure of the non-assimilated tracer, 51 chromium to track with the assimilated tracer (14C)BaP. Effects of increased sediment concentrations on AEs were not different above a BaP concentration range of 1.45 to 43.3 nmol per g. There are 43 references.

The summer stratification of the surface layer of Hood canal resulted in a surface layer low in nutrients and a deep layer low in dissolved oxygen and enriched in nutrients. Deviations from a linear nutrient:oxygen inverse relationship were observed and attributed to chemical adsorption, replenishment of nutrient pools of sinking nutrient-deprived algae and denitrification. The iron concentrations of suspended particulates in Hood canal were controlled by their aluminosilicate content and the resuspension of iron-rich sediments. Dissolved manganese entered the water column in Hood canal and was oxidized and incorporated into particulate matter. Biological growth and decay processes controlled dissolved zinc throughout much of the water column. Trace metals were taken up by organisms in the surface layer and regenerated in the deep layer.

Samples of water and of aquatic organisms were analysed for polyaromatic hydrocarbons (PAH). Significantly higher total concentrations of these compounds were found at the urbanized site, but the concentrations in the water did not cause significant mortality to caged grass shrimp (Palaemonetes pugio) and mummichogs (Fundulus heteroclitus). The undisturbed estuary showed significantly greater fluctuations in salinity, dissolved oxygen, and pH value than the urbanized estuary; further studies were required to ascertain the reasons for this.

In seven of the 8 regions studied in 1986, there was good agreement between observed and predicted copper concentrations. In the most landward region, the discrepancy between the 2 values was attributed to the presence of a previously unidentified source of copper. The model also correctly predicted a decrease in dissolved copper concentrations in the region of Seattle between 1981 and 1986 as a result of pollution abatement programmes. There are 36 references.

These were generalized extreme value(GEV), gamma(GAM), lognormal(LON), generalized Pareto(PAR), and generalized logistic distribution. The method permitted the choice of a distribution and gave the probability of it being correct. It could not be used for single station data.

A rapid high performance liquid chromatography (HPLC) screening method that involved measuring fluorescence at wavelength pairs for 2- and 3-ring oil-related aromatic compounds was used, and the concentrations of individual aromatic compounds were determined by gas chromatography/mass spectrometry (GC/MS). The results obtained by the 2 methods are tabulated. They showed good correlation, confirming the usefulness of the screening method for estimating concentrations of ion-related aromatic compounds in sediments. Difference in HPLC chromatographic patterns between sediments suggested different sources of contamination (crude oil or diesel oil) but the GC/MS results confirmed that the Exxon Valdez oil was the principal source of contamination in many of the sediments.

The study site was chosen because of local Diporeia abundances. Benthic-pelagic coupling was quantified using a combination of field measurements and an experimental approach using microcosms to determine assimilation and respiration rates for both Diporeia and sediment microheterotrophs. There was evidence of strong energy coupling between the spring diatom bloom and Diporeia. There are 49 references.

High-performance liquid chromatography was used as a rapid screening method to detect parent aromatic compounds and their alkyl homologues in sediments and polar metabolites of aromatic compounds in bile of the most common fish. Aromatic compounds were found in many of the samples of both sediment and fish bile. Results of the screening tests were confirmed in selected samples by gas chromatography and mass spectrometry, which identified the presence of petroleum-related compounds such as alkyl phenanthrenes and dibenzothiophenes.

N1 - Last updated - 2011-12-12 ER - TY - RPRT T1 - AMENDMENT NO. 4, ATLANTIC SEA SCALLOP FISHERY MANAGEMENT PLAN (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MAY 1982). AN - 36404921; 3899 AB - PURPOSE: An amendment to the management plan for the sea scallop fishery of the Atlantic Ocean is proposed. The management unit consists of sea scallop resources from the shoreline to the outer boundary of the Exclusive Economic Zone. The principal resource areas extend from the northeast peak of Georges Bank westward to the Great South Channel and southward along the continental shelf of the mid-Atlantic. The five resource areas generally defined within the management unit are Delmarva, New York Bight, the South Channel and the southeast part of Georges Bank, the northeast peak and northern part of Georges Bank, and the Gulf of Maine. The Delmarva area includes scallops as far south as North Carolina. The overall objectives of the original management plan, implemented in May 1982, are to restore adult sea scallop stock abundance and age distribution; to increase yield per recruit for each stock; to evaluate plan research, development, and enforcement costs; and to minimize adverse environmental impacts on sea scallops. This draft supplement to the final EIS of May 1982 proposes to change the way Atlantic sea scallops are managed. In place of the current meat count (size) controls, the amendment would seek to control the aggregate fishing effort through a schedule of aggregate schedule reductions. Provisions would include granting permits to qualifying vessels, dealers, and captains of vessels, and establishing a moratorium on scallop permits in order to cap the number of vessels fishing for scallops while the effort control program was in place. The effort control program would place limits on the number of days that vessels can spend at sea fishing for scallops. The fishing effort would be reduced from current levels over a seven-year period until overall mortality fell below specified levels. Permitted vessels would be placed in one of three groups based on annual days at sea during 1985-90; vessels in each group would be allocated the same number of days, based on the overall condition of the fishery. POSITIVE IMPACTS: The amendment would reduce the current rate of fishing mortality, which is unacceptably high, and would replace the fish count standard with a standard that is easier to monitor and enforce. NEGATIVE IMPACTS: The imposition of effort controls would restrict the immediate commercial capacity of the fishery, causing short-term economic hardships for some users. Some jobs would be lost if vessels excluded from the scallop fishery did not switch to an unregulated species. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

The landfill would support new container terminals, liquid bulk facilities, and dry bulk facilities. The newly created lands and the facilities they would support would be identified as Pier 400. Similar facilities would be relocated on existing lands on Pier 300. The dredging would be conducted in four increments through the year 2005 to create or improve channels within San Pedro Bay. The proposed increments are as follows: (a) deepening the existing 51-foot approach channel, constructing a new channel to Pier 300 to a depth of 63 feet, and disposing of the dredged material to create 143 acres in the Pier 400 area, a 25-acre transportation access corridor to Pier 400, and 91 acres of shallow fill along the San Pedro Breakwater and access corridor; (b) deepening the main channel to Pier 400 from 63 to 81 feet and the south channel from 45 to 75 feet, and expanding Pier 400 by 337 acres; (c) extending the new channel from the end of Piers 300 and 400 to the container terminal area of Piers 300 and 400 at a depth of 45 feet, and expanding Pier 400 by 55 acres; and (d) extending the new channel from the container terminal area of Piers 300 and 400 to the proposed new container terminals on Pier 400 at a depth of 45 feet, and expanding Pier 400 by an additional 22 acres. Throughout the early planning stages of the project, similar changes were considered for the port of Long Beach; however, in October 1991, the port withdrew from the process. POSITIVE IMPACTS: Increasing the capacity of Los Angeles Harbor would help satisfy existing and anticipated demand for the port's facilities, which stems partly from increased trade with Pacific Rim nations. Safety within the harbor would be enhanced due to wider waterway turning capacity. NEGATIVE IMPACTS: Dredging and disposal of dredged material would result in temporary localized turbidity and the permanent loss of shallow and soft-bottom habitat. Waters that have high fish nursery value and that have been identified as critical habitat for the foraging activities of the California brown pelican and the endangered California least tern would be lost to the landfill. Increased ship traffic within the harbor would increase the potential for accidental leaks or discharges and oil spills.

AN - 36414896; 3913 AB - PURPOSE: The implementation of an amendment to the fishery management plan for the waters off Puerto Rico and the U.S. Virgin Islands is proposed. This draft supplement to the final EIS of February 1985 analyzes the effects of expanding the scope of the original plan by incorporating important components of the deep-water reef fish fishery and the marine aquarium trade into the management unit and adding approximately 120 species to the management unit, which currently contains the 64 most commonly landed species. The plan would be retitled to cover all reef fishes. Other proposed management measures would restrict the collection of marine aquarium fishes to hand-held dip nets and slurp guns; specify that fish traps be constructed with two escape openings, utilizing wire panels and degradable fasteners; require an annual permit for and the periodic reporting of the sale of reef fish, including marine aquarium fish; prohibit the harvest or possession of jewfish in the management area; prohibit the harvest of specified marine aquarium fishes; recommend that the local government close a spawning aggregation for tiger grouper in waters near Vieques Island to all fishing from February through April each year; close additional red hind aggregation areas during the December-through-February spawning season; prohibit the harvest of mutton snapper in a spawning aggregation area off St. Croix from March through June each year; establish marine coral reef reserves at strategic locations to be specified in a future amendment; and prohibit the unauthorized introduction of exotic species into marine waters. POSITIVE IMPACTS: The restrictions would help prevent overfishing and would restore stability to fisheries in the area from the shoreline to the edge of the insular platform; catch rates have declined in this area in recent years. Restrictions imposed on marine aquarium species would protect those species as well as others; the most widely used collecting methods employ chemicals that could damage the reef habitat and kill associated fishes and invertebrates. NEGATIVE IMPACTS: Although the proposed conservation measures would eventually benefit the commercial fishing and aquarium fish industries, both industries would experience short-term economic hardships from the restrictions. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

AN - 73395335; 1335176 AB - A comprehensive methodology has been developed for obtaining and using smoke toxicity data for fire hazard analysis. This bench-scale method can simulate diverse fire conditions and identify extremely toxic smoke under both pre- and post-flashover conditions. However, incidence data show that most of the fire deaths in the U.S. occur outside the room of fire origin from smoke and toxic gases that are generated from a fire under post-flashover conditions. Therefore, the most relevant real-scale combustion conditions to simulate in the bench-scale apparatus would be the post-flashover conditions which are achieved by using radiant heat, a high heat flux, and correcting the bench-scale carbon monoxide (CO) results to agree with CO yields observed in real-scale post-flashover fires. The number of test animals (Fischer 344 male rats) is minimized by using the N-Gas Model to estimate the LC50 value from the chemical analysis of the smoke. The current N-Gas Model predicts the toxicity of complex fire gas mixtures based on a large data base of experimental results of individual and mixed gases that include CO, CO2, reduced O2, HCN, HCl, HBr, and NOx. The prediction is checked with a small number of animal tests and an approximate LC50 value is determined. The bench-scale results have been validated with full-scale room wall burns of a limited number of materials of widely differing characteristics chosen to challenge the system. The toxic potency values are assessed to determine if the smoke from a material or product is unusually or extremely toxic and can then be used in computations of fire hazard.

AN - 62773533; ED361254 AB - This teaching supplement from the U.S. Census Bureau is designed for educators in grades 5 through 12. The Bureau offers it as a way of addressing the needs and concerns of teachers as they attempt to include statistical information about the everyday world in an effort to meet new educational standards. The supplement is presented in order to introduce the "Statistical Abstract of the United States," a national information resource published by the U.S. Government since 1878. A sort of statistical almanac, the abstract contains more that 1,400 data tables and charts including topics such as housing, nutrition, health, the economy, the trade balance, and the environment. This supplement illustrates the content and provides a sample of the types of information contained in the abstract. In addition it supplies the teacher with suggestions for classroom activities and with explanations of various statistical concepts which teachers will find helpful no matter what data volume they use. The teacher's guide includes the contents of the 1992 statistical abstract and brief guides to demographic statistical concepts and socioeconomic statistical concepts. Illustrations present information on (1) land cover/use in the United States; (2) hazardous waste sites on the national priority list from 1991; (3) resident population in April of 1990; (4) mean money earnings by educational attainment and sex; and (5) immigration to the U.S. from 1820 to 1990. Eleven examples of statistical abstracts are given. (DK) Y1 - 1992/12// PY - 1992 DA - December 1992 SP - 33 PB - Customer Services Branch, Dept.

These compounds play an important role in (1) shaping global tropospheric chemistry, (2) regional photochemical oxidant formation, (3) balancing the global carbon cycle, and (4) production of organic acids which contribute to acidic deposition in rural areas. Present estimates place the total annual global emission of these compounds between approximately 500 and 825 Tg yr (super -1) . The volatile olefinic compounds, such as isoprene and the monoterpenes, are thought to constitute the bulk of these emissions. However, it is becoming increasingly clear that a variety of partially oxidized hydrocarbons, principally alcohols, are also emitted. The available information concerning the terrestrial vegetation as sources of volatile organic compounds is reviewed. The biochemical processes associated with these emissions of the compounds and the atmospheric chemistry of the emitted compounds are discussed. Copyright 1992 by the American Geophysical Union.

Emissions from tillage of soils were estimated from the work of previous researchers. The area of maximum dust production by all of those sources is the area of the old "Dust Bowl" of the 1930s (the panhandles of Texas and Oklahoma, eastern New Mexico and Colorado, and western Kansas). The areas of maximum alkaline dust production are the arid southwest, the "Dust Bowl," and the midwestern-mideastern states from Iowa to Pennsylvania. Our calculations show that calcium is the dominant alkaline element produced by "open sources" (sources too great in extent to be controlled by enclosure or ducting). Although the largest dust mass source is wind erosion (by winds associated with regional activity and convective activity), the largest producer of the alkaline component is road dust because the abundance of alkaline materials in road coverings (which include crushed limestone) is significantly higher than for soils. Comparing the above estimated sources of alkaline material with inventories of SO (sub 2) and NO (sub x) emissions by previous investigators gives the rough approximation that alkaline emission rates are of the order of the SO (sub 2) + NO (sub x) emissions in the western United States and that they are much smaller than SO (sub 2) + NO (sub x) in the eastern United States. This approximation is substantiated by data on Ca/(SO (sub 4) + NO (sub 3) ) for wet deposition for National Atmospheric Deposition Program sites. Copyright 1992 by the American Geophysical Union.

Cycles with periods near 23,000, 41,000, and 100,000 years dominate this climatic narrative. When the narrative is examined in a geographic array of time series, the phase of each climatic oscillation is seen to progress through the system in essentially the same geographic sequence in all three cycles. We argue that the 23,000- and 41,000-year cycles of glaciation are continuous, linear responses to orbitally driven changes in the Arctic radiation budget; and we use the phase progression in each climatic cycle to identify the main pathways along which the initial, local responses to radiation are propagated by the atmosphere and ocean. Early in this progression, deep waters of the Southern Ocean appear to act as a carbon trap. To stimulate new observations and modeling efforts, we offer a process model that gives a synoptic view of climate at the four end-member states needed to describe the system's evolution, and we propose a dynamic system model that explains the phase progression along causal pathways by specifying inertial constants in a chain of four subsystems. "Solutions to problems involving systems of such complexity are not born full grown like Athena from the head of Zeus. Rather they evolve slowly, in stages, each of which requires a pause to examine data at great lengths in order to guarantee a sure footing and to properly choose the next step." --Victor P.

This paper uses wind, hydrographic, and ocean remote sensing data to examine southwest monsoon controls on the foraminiferal faunal composition of Recent seafloor sediments of the northwestern Arabian Sea. Ekman pumping resulting in open-ocean upwelling and coastal upwelling create two distinctly different mixed layer plankton environments in the northwestern Arabian Sea during the summer monsoon. Open-sea upwelling to the northwest of the mean July position of the Findlater Jet axis yields a mixed layer environment with temperatures of less than 25 degrees C to about 26.5 degrees C, phytoplankton pigment concentrations between 1.5 and 5.0 mg/m (super 3) , and mixed layer depths less than 50 m. Convergence in the Ekman layer in the central Arabian Sea drives the formation of a mixed layer that is greater than 50 m thick, warmer than about 26.5 degrees C, and has phytoplankton pigment concentrations generally below 2.0 mg/m (super 3) . Coastal upwelling creates an extremely eutrophic plankton environment that persists over and immediately adjacent to the Omani shelf and undergoes significant offshore transport only within topographically induced coastal squirts. The foraminiferal faunal composition of upper Pleistocene deep-sea sediments of the northwestern Arabian Sea are mainly controlled by vertical nutrient fluxes caused by Ekman pumping, not coastal upwelling. Transfer functions for late Pleistocene mixed layer depth, temperature, and chlorophyll have been obtained through factor analysis and nonlinear multiple regression between late summer mixed layer environment and Recent sediment faunal observations.

Observed changes in suspended sediment concentration were modeled with a simple zero- dimensional, spatially averaged, mass balance model in which local bottom erosion was expressed as a linear function of the bottom shear stress. Estimates of the three parameters required by the model (particle settling velocity, resuspension concentration, and background suspended material concentration) are reasonably consistent for the various data sets, suggesting that the properties of the lake bottom do not change significantly through either space or time. The modeled settling velocities agree with the observed suspended particle size data and the erosion rates are comparable to laboratory results for freshwater sediments. The results show that a simple mass flux model can be used to model local sediment resuspension events in Lake St. Clair with reasonable accuracy.
